Diggers & Mining. Diggers and miners. Many diggers not only moved from field to field, but alternated between gold digging and other occupations. Slide; THE STATE OF VICTORIA - - - Gold digging and other sorts of labour have arrived at a sort of equilibrium; and streams of people are now flowing from the one occupation to the others, and visa versa. A few weeks ill luck at Bendigo disgust a man with his auriferous well sinking and he goes into some sort of service. A dispute with his master chiming in with some current takes of mining success sends him back to the diggings again; and so the stream flows backwards and forwards keeping - - - the wages of all kinds of labour at an equilibrium - - - (M.M.H., August 19, 1853) Markings: 46 994:LIF I.

The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while known masses are added to the other plate until static equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. Medication given to patients at both Aradale Mental Hospital and J Ward had their does measured using these weights and scales - and some evidence of residue remains.The scales are in excellent condition and a good example of medical equipment used in Aradale Mental Hospital and J Ward.

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. The amount of fine fuel available can increase rapidly from nearly zero when fuel moisture content is more than 16% after rain or a heavy morning dew, to many tonnes per hectare as fuel dries out later in the day and the moisture content drops below 9%. This explosive escalation in the amount of available fuel can happen over a few hours on hot and windy days. This device is used for determining air temperature and relative humidity. It contains two thermometers, one of which is covered with a wick saturated with ambient temperature liquid water. These two thermometers are called dry bulb and wet bulb. Once the thermometers to reach equilibrium temperatures the two thermometers are quickly read. The figures are then used to convert the dry bulb temperature TDB and the wet bulb temperature TWB into humidity information. The wet bulb temperature is approximately equal to the adiabatic saturation temperature.

A sling psychrometer is a simple device for determining air temperature and relative humidity. It contains two thermometers, one of which is covered with a wick saturated with ambient temperature liquid water. These two thermometers are called dry bulb and wet bulb. When the sling psychrometer is spun rapidly in the air, the evaporation of the water from the wick causes the wet bulb thermometer to read lower than the dry bulb thermometer. After the psychrometer has been spun long enough for the thermometers to reach equilibrium temperatures, the unit is stopped, and the two thermometers are quickly read. A psychrometric scale on the side of the instrument is then used to convert the dry bulb temperature (TDB) and the wet bulb temperature (TWB) into humidity information. The wet bulb temperature is approximately equal to the adiabatic saturation temperature. The thermometers fold back into the plastic handle when not in use.

The Portland Social Amusement Club was founded in 1897. Taken from Trove. Portland Guardian Monday May 26 1913: Portland Social Amusement Club. The members of the above Club celebrated the 16th anniversary of its foundation on Tuesday evening last, when the usual banquet. and social gathering was held. During the afternoon, a numerous band of the lady members attended at the, Free Library Hall and made the necessary arrangements, so that on arrival at the scene at 8 p.m. those attending were very pleasurably surprised to find most taste fully decorated tables actually groaning with the weight of all those good things which appeal so strongly, it is said, to the average man, and perhaps we may also add, woman also. At any rate, he would indeed be hard to please, who was not fully satisfied with all that was placed before him on that eventful evening. The attendance this year overtopped that of previous years, as over 80 ladies and gentlemen took part in what must be considered as one of the most successful of the many 'successful gatherings that have taken place. This 16th anniversary was the 431st ordinary gathering that had occurred, and, as the President (Mr. F. A.Row) justly said, it would appear that the Club, which many years ago was given but six months live, had proved the falsity of the attempted prophecy. After the principal business of the gathering had been transacted, the usual Club dinner speeches were made. The President gave "The King," which after being duly honored, was followed by the principal toast of the evening, "The day we celebrate." To Mr D. McDonald the toast of the Absent and Foundation members was entrusted, and as usual, that veteran discharged his duty well. II i cferred to the fact that of the 34 foundation members who started the Club in 1897,only five were present that evening. Mr W. T. Bennett, as one of the five referred to, responded, and hoped that in the glorious future that appeared before Portland, the Club, which had been started in the days of its adversity, would flourish in a like manner. Mr Grant proposed the toast of "Our Visitors." and in the name of the Club welcomed them to this the most important gathering of the year. Mr J. R. Woods responded in his usual happy way, and acknowledged that, until he had been the Club's guest during the years of his mayoralty of the town, he had no idea that it had enrolled among its members the number of ladies and gentlemen that it had or that its functions were upon the scale that he had since found to be the case. Mr G. H. .ennett upheld the claims of the ladies, especially those belonging to the Club. He evidently spoke with much feeling, and. waxed more than usually poetical in his eulogy of the graces and skill of the gentler sex. He rather upset the equilibrium of three of the younger portion of the gentlemen present by asking them to respond, but they all managed to "upstand" and make their acknowledgments. Mr T. F. Cruse was particularly happy in proposing the toast of. "The President and Members of Committee," who, he claimed, had done so much towards the success of the Club, and were deserving of the best that the members could give. Mr T. E. C. Henry, upon the invitation of the .President, responded,-end pointed out that [whilst it might appear that the work of the committee was light, it was not so in reality, as any member who desired a seat upon the Board would soon find out after.his or her election. The singing of Auld Lang Syne brought this portion of the entertainment to a close. In the dance which followed, some opportunity to view the ladies' dresses was afforded, and it could then be easily seen that the anniversary gathering of the Club was considered by the lady members at least, if not .by others, to be important enough to demand special treatment in the matter of dress. Many elaborate and beautiful costumes graced the scene, and everyone appeared to thoroughly enjoy themselves. The function was kept going merrily until about 2 a.m.; when the break up occurred. During the gathering telegrams of con gratulation were received from Mr W. B. Shevill and also from Mr Jno. Homers, both old members, the former a foundation one. Mr O'Donnell apologised for his own and Mrs O'Donnell's absence.Photograph of Portland Social Amusement Club
