Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Whalebone The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The bone of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as whalebone. Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

The wooden pattern is part of a set that is stored in a strong wooden crate and may be part of another similar pattern. It was used at Briggs’ Brass Foundry for making sand casts. The traditional craft of sand casting is over 2000 years old. The handcrafted process produces brass and copper alloy goods that are well suited to marine use; bells, boat hooks, cowls, propellers, handles, lids, rowlocks, hooks, letters, bolts, rail holders, brackets, deck plates, flanges, rudder guides, portholes and covers. Briggs’ Bronze mixture is a copper-based alloy made from local ingots of copper, tin, zinc and lead in carefully measured quantities. The finished product is non-ferrous and can last indefinitely. The crate of patterns was donated by the Briggs family in the early years of Flagstaff Hill, along with other related items such as brassware, tools and machinery. The donated items were displayed in a simulated Brass Foundry in the Village along with other working crafts, trades and services found in a Maritime town. The items were on show from the completion of the building in 1986 until 1994 when the building was repurposed. The patterns represent the trades of foundering and metalwork, both supporting maritime industries such as shipwrights and boatbuilders. Farmers, manufacturers and other local industries also needed the castings made by foundries. The Brass Foundry included a historic Cornish chimney set up as a working model, to tell the story of smelted metal heated in furnaces then be poured into the sand moulds. This chimney was made from specially curved bricks and is now about two-thirds of its full height when originally located at the Grassmere Cheese factory. The hand-cast sand patterns hold considerable significance due to their association with Briggs Brass Founders, a firm established in the early 20th century and widely recognised for its expertise in producing, repairing, and restoring ship bells and marine equipment. Known for their specialisation in non-ferrous metal casting, Briggs Brass Founders supplied high-quality fittings and equipment for maritime use. The company extended its operations by opening a branch in Warrnambool, where it actively supported the local community. The foundry’s ability to cast essential products was important to local and regional industries, like fishing, farming, manufacturing and commercial businesses. Through its presence, its reputation was reinforced as both a skilled manufacturer and a community-minded enterprise. The foundry is notably associated with the Schomberg Bell at Flagstaff Hill, having restored this small, historic bell to its original condition. The Schomberg Bell is a fine example from a luxury migrant vessel dating back to the mid-19th century, reflecting the craftsmanship and heritage preserved by Briggs Brass Foundry.

The wooden pattern forms part of a larger collection, securely stored within a durable wooden crate. This pattern was an essential tool at Briggs’ Brass Foundry, specifically designed for creating sand casts. Sand casting is a time-honoured technique, with a history exceeding 2,000 years. The handcrafted nature of this process results in the production of brass and copper alloy items, which are particularly suitable for maritime applications. Typical products include bells, boat hooks, cowls, propellers, handles, lids, rowlocks, hooks, letters, bolts, rail holders, brackets, deck plates, flanges, rudder guides, portholes and covers. The distinctive bronze mixture used at Briggs’ Foundry is copper-based, composed of local ingots of copper, tin, zinc and lead, blended in precisely measured quantities. The resulting alloy is non-ferrous, known for its exceptional durability and longevity. In the early years of Flagstaff Hill, the Briggs family generously donated the crate of patterns along with other related items such as brassware, tools and machinery. These items were prominently displayed in a simulated Brass Foundry within the Village, alongside other working crafts, trades and services typical of a maritime town. From the completion of the building in 1986 until its repurposing in 1994, visitors could view these items and gain insight into the foundering and metalwork trades that supported maritime industries, including shipwrights and boatbuilders. The castings produced at the foundry were also vital for farmers, manufacturers and other local industries. The Brass Foundry display featured a historic Cornish chimney, constructed as a working model to illustrate the process of smelting metal in furnaces and pouring it into sand moulds. The chimney, crafted from specially curved bricks, currently stands at approximately two-thirds of its original height, having previously been located at the Grassmere Cheese factory. The craft of sand-casting, which utilises intricately carved wooden patterns to create metal objects, stands as a testament to the enduring value of traditional skills. This age-old technique remains relevant today, linking past craftsmanship to ongoing industrial practices. The foundry pattern set holds particular significance due to its strong associations with brass foundries, both locally and in coastal regions across Victoria. In these areas, marine industries such as ship and boat building have long depended on high-quality metal castings for the machinery, equipment, and fittings essential to their operations. The alloys formulated by Briggs Brass Foundry, crafted from non-ferrous metals, were specifically designed to provide superior longevity and durability in maritime environments. These patterns are closely tied to the history of the Briggs Brass Foundry, a respected and long-running company that specialised in producing cast goods for the marine sector. The foundry was equipped to supply both unique, one-off items and mass-produced components, ensuring that its products found their way onto a variety of sail and steam vessels along the Victorian coast, including in Warrnambool. In addition to its broader marine applications, Briggs Brass Foundry established itself as a bell-founder specialist. The company’s expertise is notably linked to the historic Schomberg Bell at Flagstaff Hill, which they restored to its original splendour as a fine example of a bell from a luxury migrant ship of the mid-19th century. The significance of the pattern set is further heightened by its association with Briggs Brass Founders, a firm established in the early 20th century and widely recognised for its proficiency in producing, repairing, and restoring ship bells and other marine equipment. Renowned for their non-ferrous metal casting, Briggs Brass Founders consistently supplied high-quality fittings and equipment vital to maritime pursuits. Moreover, the company expanded its influence by opening a branch in Warrnambool. Through this local presence, Briggs Brass Founders supported the regional marine industry and forged strong connections with fishermen and businesses. This not only reinforced their reputation as skilled manufacturers but also highlighted their commitment to community engagement and support. Pattern; hexagonal wooden shape painted orange.

Thomas Walker & Son was internationally renowned in the manufacturing of ships logs. Founding father Thomas Walker (1805–1871), an engineer in Birmingham, patented a mechanical log in 1878 which was a recording instrument that attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kick starting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ships log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (British-based organisation promoting ties and trade with the British Caribbean) and the most common log in use for two generations. It took till 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By the time of his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log and the Walker factory was one of the first to introduce the 48 hour work week for employees. This ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades. Ship Log, three analogue dials calibrated in increments of Miles, the Rocket Log is a nautical instrument for measuring a vessel’s speed and distance traveled. The floating log was drawn behind the ship over a fixed time period in order to measure the distance traveled. The counter could measure enough miles to cover the maximum distance traveled by a ship in one day. The log has two distinct parts; a brass register, made by Walker, showing the distance recorded and the rotator made by Reynolds, that spins in the water driving the counter. both parts are connected by a linked chain. The register has a cylindrical brass body approx 4.5 cm diameter containing registering mechanism with hardened steel bearings. Distance is indicated by the three pointers on enamel plate as follows: graduated every 10 miles from 0-100; every mile from 1-10; every 1/4 mile from 1/4 -1. A brass sling and eye secured to the body enables it to be attached to the taffrail. The original rotator would have had a cylindrical tapered wooden body, approx 4.5 cm in diameter with three metal alloy fins or could be all made from brass. A towing eye is fitted to the tapered end. The two pieces of apparatus are connected by a length of linked chain, length 22.9 cm."Walkers Rocket Ship-Log Birmingham (Patented)" printed on face-plate.

In times past the only way to measure a ship’s speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this, they could estimate the vessel's speed through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. Various manufacturers of nautical equipment had sought over the years to perfect the operation of determining a ship's speed and it wasn't until Thomas Walker and his son Ferdinand developed a mechanical system that eventually made this task became easy for marine navigators.
