CAst iron lace was made in foundries in most cities. There were 42 such foundries in Melbourne alone. It was cheaper to make than wrought iron. "Pig iron"' iron ore, was melted in a blast furnace, mixed with alloys and poured into moulds usually made with sand. The alloys needed a minimum of 2% carbon.Black and White photo by A Doney of Balustrade on property on the corner of Forest and Barnard Streets Bendigo.A Doney Bendigoalan doney, bendigo, wrought iron, forest street bendigo, barnard street bendigo

The lead line or hand lead is a simple navigational instrument used as a depth finder to measure the depth of water under the ship’s keel and to take samples of the sea bed. The long line may be marked at regular intervals with tags of different coloured and textured fabric, such as rope, leather and cloth. Each tag was a code to represent a certain depth. The leadsman’s eyes and hands could distinguish the depth easily as he drew in the lead line, day or night and in poor weather conditions. A standard set of codes for the tags was used so that the depth of the sea could be easily and quickly read. The measurement used was a Fathom, which equals 1.83 metres. The codes were: - 2 fathoms = 2 strips of leather 3 fathoms = 3 strips of leather 5 fathoms = white duck fabric 7 fathoms = red bunting fabric 10 fathoms = leather with a hole 13 fathoms = blue serge fabric 15 fathoms = white duck fabric 17 fathoms = red bunting 20 fathoms = 2 knots The lead weight could be between 7 -14 pounds (3.5 – 6.5kg) and the rope would be approximately 25 fathoms (45m). The hollowed-out end of the weight would hold a stick substance such as tallow or wax, which would pick up samples from the sea bed which would show whether the vessel was close to, or far away from, the shore. The leadsman would stand at the front of the vessel and cast the lead line into the sea. When it hit bottom he would note the tag marker nearest the surface of the water and call out his finding. Then he would haul it up again and examine the kind of matter that adhered to the end of the weight, whether it be sand, mud, gravel, or the colour of it. This information would be given to the ship’s helmsman or navigator and would help indicate the proximity to the land.This handheld lead is an example of early marine navigational equipment used by sailors to travel the seas to measure the depth of the water and sample the nature of the seabed. It helps to understand the history and progress made from the very basic to the sophisticated technology of today.Lead line, sounding line or depth finder. The long length of rope has a heavy lead weight attached to the end. Coloured fabric tags are tied onto the rope at regular intervals, representing different depths. The concave base of weight holds sticky substances such as tallow or beeswax, providing an adhesive surface to collect samples of sea bed like sand, shells or pebbles. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, lead line, depth finder, hand lead, sounding lin, leadsmane, navigation instrument, leadline, hand lead line
