92 YEAR-BOOK OF FACTS. 



the stove being air-tight, the draught is certain, and ashes may be 

 burnt over and over again until reduced to clinkers ; fifth, the flues 

 will £ro two or three months without clearing ; sixth, the flues are all 

 complete in the stove, and consequently no masonry is necessary 

 for fixing, except for appearance ; seventh, roasting by the open fire 

 does not interfere with the baking of the oven ; eighth, direct con- 

 sumption of fuel is so regulated by the valve in the ashpit door, 

 that the fire may be kept in all the night ; ninth, the hot closet 

 below keeps viands hot after being cooked, or warms plates ; tenth, 

 boilers can be fixed so as to be moveable without interfering with 

 the fixings of the stove ; eleventh, meat baked in this stove cannot 

 be distinguished from roast meat ; and twelfth, it is an infallible cure 

 for a smoky chimney. 



WIND-ENGINES. 



Mr. Peill, of New Park-street, Southwark, has introduced an 

 arrangement of Engine driven by Wind, which answers many useful 

 purposes on farms and in other situations ; as, on a farm where beasts 

 are stall-fed, or in a yard, where it would very soon pay for itself in 

 the labour of pumping water for the supply of the cattle. For cutting 

 chaff, too, it is most useful ; the saving effected by cutting hay and 

 straw into chaff is well known, for it prevents a great deal being 

 wasted, and also where sheep are fed on land it is serviceable. 

 The supply for cattle being required in winter, the engine comes into 

 action very frequently, and if placed on a barn, two men can be em- 

 ployed when they can do nothing out of doors, anil, in a few hours, 

 cut chaff and roots enough to last for a week. A wind-engine of f -horse 

 power, with one of Messrs. Warners' pumps attached, erected nearly 

 half a mile from the premises, pumps the water from a spring to the 

 height of 70 feet, supplying the house and farm-yards, and filling a 

 pond that has been dry for years. It requires very little wind, and 

 owing to the sails being self-adjusting, no attention save oiling once 

 a week. — Abridged from Communications to the Mechanics' Magazine. 



pneumatic despatch company. 

 At a recent meeting of shareholders of this Company, held at 

 Westminster, the chairman, Captain Huish, in the course of the 

 proceedings, said they were continuing experiments, not to ascertain 

 the power of propulsion by exhaustion, but to ascertain the means 

 by which they could produce a revenue at the lowest possible cost. 

 The experiments had shown most satisfactory results ; and a tabu- 

 lated statement has been furnished bj the engineers to the board. 

 The engineers had already informed bun that, by the "■"' of the Fan. 

 which was a most elaborate tbing, but very economical, they could 

 obtain a speed of thirty or forty miles at a very inexpensive cost.

Bloomsbury for post-office purposes.
