Romantic, charming . . . ''SUNNYBROOK'' ON the slope of a hill on the East side of Bolton street and overlooking willows that trail gracefully in a creeklet which shows no great haste to blend with Diamond Creek and so to the Yarra, there stands a great old-fashioned home. Outwardly it speaks of past opulence rather than beauty of design, but the velvet green lawns and the formal neatly weeded rose gardens, the well established trees, tennis courts, wisteria covered pergolas and the great curved fronds of old palms produce an atmosphere that cannot be built-up in less than decades. Here is irresistible old-world charm. The jangle of today cannot penetrate ... it is a place to remember ... a place where events to be remembered have a perfect setting ... it is "Sunnybrook." From the neighbouring ‘Beranto Lodge’ Mrs. Lenne can catch glimpses of ‘Sunnybrook,’ but the old home is well hidden from all quarters and only the faultlessly kept lawn can be seen by the curious. Like many other people, Mrs. Lenne was curious. Who can blame her. ‘Sunnybrook’ is a name to conjure with in Eltham. When the elderly men of the township were young bucks ‘Sunnybrook’ stood alone, a proud home that was known and established. Amongst the simple homes of the valley of the Diamond Creek, ‘Sunnybrook’ was Queen. In the roistering days of the Diamond Valley, when Kangaroo Ground was the seat of the Shire and when five pubs dotted the road from Lower Plenty to the civic centre, ‘Sunnybrook’ was off the track of the boisterous and tipsy. ‘Sunnybrook’ is still off the beaten track . . . but only slightly so; it no longer looks over cow pastures, but the neat, newly built houses which dot the length of the Main Road. They are still no closer than half a mile and while these houses have sprung up the fine trees and shrubs have quietly closed in around the boundaries of ‘Sunnybrook' as if to keep the old place to itself. That is how it has become something to whet the curiosity. When the course of events put the place on the market Mrs. Lenne bought it. When a modern house is bought it is pliable in the sense that the owner moulds it according to personality. It can remain severe, utilitarian and with a little neglect soon run to an ugly shabbiness. But with old 'Sunnybrook' it is different. There is in existence a character indelibly written into every line of the place . . . it is a LOVE OF ENGLAND. Upon ‘Sunnybrook’ has been lavished the devoted love of England to such a degree that it must be seen. The gardens and lawns are formal, and though lovely and speaking of the leisure of past years they are not English . . . they are just lovely, with the beauty that only the long established seem to possess. It is inside ‘Sunnybrook’ that the intense love of England is seen. Years ago the home was bought by a Mr. Martin, who was getting on in years, as a home for his much younger wife. The couple spent thousands of pounds as well as endless care and imagination in the complete redecorating of their home. Oak panelling imported from England was built in. Huge fireplaces shed their Colonial appearance to be become the fireplaces of England . . . and they were so in every sense because they were also imported from England. One lovely specimen whose gracious lines are remarked upon by all who see it, is a certified antique of finest English Oak. Care was taken to see what hand made wrought iron light fittings were in keeping. The old place has three lounge, dining or living rooms according to taste and requirements, and all are bigger than the biggest attempted in a “big” modern home. This does not include an outside living space of ample proportions, all fine flywired in and enclosing a fernery. A turn of a tap and spray as fine as mist is released over the rockery. On a scorching summer day when no relief short of a swim could help ordinary people, the resident of ‘Sunnybrook’ found the coolness of a dell in which to sit and enjoy their evening meal. What is more, the temperature of the whole house could be reduced by merely turning on this extensive spray water system. Yes, comfort to luxury standard is built in. And what happens to 'Sunnybrook' now? Mrs Lenne is famous to thousands for her quite fabulous catering. Her home and her "Wanda Inn" at Hepburn Springs have long been a Mecca for those who want the different in catering . . . different in the sense that every client is treated as a friend, not a customer and the hospitality and attention one would give to an honoured friend is accorded. And the food! – ask anyone who has enjoyed the privilege. Ask those who attended the reception given to Mr. Menzies by Eltham Shire Council; ask those members of the Diamond Valley Chamber of Commerce who enjoyed it! [See EDHS_04736-1/2 https://victoriancollections.net.au/items/5d4c2fb521ea6727d892df72] There is only one word anyone ever uses . . . “unbelievable!” it must be seen and eaten to be believed. And ‘Sunnybrook’ will ring to the laughter, and offer its spaciousness for the fun of all who join in the happiest occasion in the life of those just married, whose wedding reception is intended to be “remembered.” Mrs. Lenne is a dynamic ball of energy whose enthusiasm is not to be brooked. She has acquired the home of her dreams. 13 March 2020 Note: Historian Stella M. Barber via the GSV members Forum cites that Clair Samwell and Doris Good ran a nursing home in Balwyn called Penquite (1946-1952). Prior to that the women had run a rest home called Beranto in Eltham.

Gas lamps worked by heating something called a 'mantle' with a gas flame. The mantle then glowed brightly, lighting up the room. Lamps had either two chains, for a ceiling-mounted lamp or a tap for a wall-mounted burner to turn off the gas. These chains or taps could also adjust the flow of the gas and hence the brightness of the mantle. Before Carl Auer von Welsbach invented the gas mantle in the 1890s, all gas lights in homes and street lights had simple gas jets that pointed upwards. In the home, these lights were covered with glass globes and had an overall ornate look making the lamp ascetically pleasing and protecting the flame from being blown out. However, this arrangement was extremely inefficient: To get as much light as possible, the gas had to be turned fully up, resulting in large sheets of flame rising towards a ceiling. Also, because the lamp had to be point upwards, the illumination was directed upwards, i.e. at the ceiling rather than where it was needed. So the usable light for a given amount of gas was minimal but the invention of the gas mantle eventually changed this. It enabled gas lights to have a small flame and to direct their light downwards. The item is significant as it is part of a very ornate gas lamp wall bracket from the late 19th to early 20th century. Its provenance is currently unknown and at this time cannot be associated with a historical event, person or place and the item is assessed as a collective asset.Gas lamp wall bracket; part of a gas lamp.

Two articles about the origin of the Last Post collected by Bill Rogers. One's source is possibly Sydney Legacy. It says the last post is derived from the old custom of beating Tattoo. This word comes from the Dutch phrase - doe den tap toe, meaning turn the taps of the taverns off. Then when bugle calls were introduced two posts were written. "First Post symbolises the inspection of the last inn in the town. It was then a simple step for the Last Post to become associated with Military Funerals. Played at funerals the Last Post is followed by the call Rouser, a later version of Reveille, which symbolises the awakening of a new life." The other has the words to the Last Post and a similar story but not as detailed. Document was from a folder of documents donated to the archive by Legatee Bill Rogers that related to his time as President (March 2006 - March 2008) or as a legatee.A record that the traditions of the military was significant to the Legatees.Two A4 pages of the origin of the Last Post, one from Sydney Legacy.tradition, last post

Dr. Joseph Clover (1825-1882), an English physician, first described his Portable Regulating Ether Inhaler on Jan. 20, 1877. Clover was an especially sought after anesthesiologist and early pioneer in the specialty. This was the best-known of many inhalers that Clover designed. The dome-shaped reservoir was turned to points on a control dial to gradually increase or decrease the percentage of the air that passed over the ether. Several inventors based new inhalers on this, while the original continued to be manufactured as late as the beginning of WWII. Clover, to spare the patient the unpleasantness of induction with his "closed" inhaler (1877), suggested the "mitigated-ether" technique. The inhaler was fitted with a bypass tap for the reception of N2O. The bag was filled with the gas and anaesthesia was inducted a combination of N2O and asphyxiation. Ether was then admitted gradually by rotation of the bowl of the inhaler. When the patient had been duly "weaned over" to ether, the mask was lifted, the N2O allowed to escape, the bag refilled with exhaled air, and normal anaesthesia "a la Clover's inhaler" was continued.Metal domed chamber with a bulb attachment for rebreather bag, including a tap mechanism. Remnants of the paper rebreather bag are attached to the bulb. At the other end is a yellow facemask made of plastic (probably celluloid). The manufacturer's logo has been moulded into the dome of the chamber.Manufacturer's logo: THE HOLBORN / SURGICAL INSTRUMENT CO.
