Artificial Incubation.

The "Sidaway " is self-regulating. The arrangement being exceedingly simple, there are no complications to 
get out of order, and the lamp can be left for twelve hours without evil effects following ; and, as the 
heat in the egg-drawer will not vary more than two or three degrees for this period, the lamp can be dispensed 
with at night, thus minimising the risk of fire — this machine is one of the best and most effective 
machines on the market. They are made in various sizes, viz., 25-egg, loo-egg, and 150-egg capacity, or 
any size to suit the requirements of purchasers. These machines are thoroughly tested before being 
sent out ; and the manufacturer, to encourage the confidence of purchasers, will at any time place 
eggs supplied in the machine ordered, and give the buyer a direct practical test of the capabilities of the 
machine in hatching the eggs, making a nominal charge for the same. This gives the purciiaser an oppor- 
tunity of having clearly demonstrated the advantages of the "Sidaway." At this establishment there is a 
very complete lamp foster-mother, with run attached, thoroughly well made, and sold at a most 
reasonable price. The advantages of a foster-mother become quite apparent when Incubators are used, and 
the " Sidaway " lamp foster-mother will be found the equal of any other. There are also various other 
foster-mothers without lamp attachment, which are quoted at very low prices, all very complete of their kind.

The Patent " Eclipse " Incubator. This machine is manufactured by the patentees, Messrs. Ellis and 
Dobeson, Bay Street, Botany, and has obtained a position in the front lank through sheer merit. One of the 
patentees is directly interested in duck-raising for market, thereby bringing his knowledge and practical 
experience to bear in the improvement and construction of this m.achine, the other patentee being a practical 
mechanic of many years' experience in the manufacture of Incubators. One prominent feature in the 
" Eclipse " Incubator is the minimum amount of oil consumed, the makers claiming that it costs but 
IS. 2ld. per month to run a loo-egg machine, and 2s. per month to run one of 200-egg capacity. This 
economic result is brought about by the means of pipe-flues running through the water in the tank, thus 
securing 370 square inches of heating surface. The tank is so formed that it gives all-round heat, top, 
bottom, and sides securing a perfect circulation to equalise the temperature in the machine. The advantage 
claimed for this system is that warm, moist air for ventilation is secured instead of cold, as in the majority of 
other machines, thus providing moisture drawn from warm water instead of cold ; and again, that the heat in 
the egg-drawer need not be higher than loi deg. Fahr., whereas top-heat machines require 104 deg. Fahr. 
The circulation is guided by means of partitions running through the tank, so as to secure equal temperature 
on the sides of the egg-drawer.
