 pers into the cylinder. The end lid having been put on and cot- 

 tered up steam-tight, the vessel is thus filled with the desired 

 material, which is spread uniformly with a fork through the man- 

 lid. Steam is then turned on ; and, when the operation is com- 

 plete the end lid is loosed and thrown up by the aid of the coun- 

 terbalance above the cylinder end, and the contents drawn out by 

 forks, or by a large but light and slender instrument like the 

 worm of the ramrod of a gun. Before being used the first time 

 the inside of this vessel is given a coat of drying oil ami copal' 

 varnish mixed, which prevents subsequent oxidation. The ge- 

 neral intent of the whole of the apparatus is to save labour and 

 fuel, which it does effectually ; and that portion of it for cooking 

 potatoes is now about being erected in the new gaol of Mayo 

 the largest in Ireland. In some few cases, where the extent of the 

 apparatus would be very great, and labour dear, it might be advisable to connect a small steam-engine 

 with it, working from the same boiler, to pump water, slice turnips and mangold wurzel, cut chaff, and

bruise oats and beans, &c. Where a high pressure steam-engine pre-exists on a farmery for other pur- 

 poses, the waste steam from it may be made fully available for steam-cooking apparatus, which thus 

 would cost nothing ; it requires, however, a particular adaptation, in order that the power of the engine 

 may not be reduced, by driving the steam through any considerable resistance. Occasionally, but rarely, 



fluids may require to be boiled 

 by steam, as stirabout for pigs, 

 or wash for calves : for these, 

 another form and construction 

 of vessel altogether is neces- 

 sary. (A. Ma/let.)

strongly recommended for pro- 

 moting the health of poultry. 

 Cold, it is found, either pro- 

 duces inflammation of the 

 lungs, or pulmonary consump- 

 tion. Heat constantly prevents 

 this, and alleviates the disease 

 when it has taken place. (An- 

 nales dcs Sciences Naturelles, 

 as quoted in Quart. Jour, of 

 Agr., vol.il. p. 568.) Warmth, 

 also, makes fowls lay. Every 

 housewife knows that eggs are 

 most abundant in warm wea- 

 ther ; and all country house- 

 wires know that the only way 

 to make hens lay in cold wea- 

 ther, when egys are dear, is to
