A Stable Ventilator.

A Waggon Jack.

The proper ventilation of stables is an iraj portant matter for those ' who are caref ir about the health of their horses. There are good methods and bad methods of ventilation, and it is essential that mistakes are not made from a want of knowledge of the objects to be attained and the evils to guard against in ventilating a building. What is wanted is a continual changing of the air as it becomes vitiated by the exhaustion of itt> oxygen, and the accumulation of the carbonic acid gas given off from the lungs of the breathing animals. The evil to be guarded against in endeavouring to obtain this continual supply of fresh air, is> the creation of draughts. The kind of combined ventilator and window for a stable here illustrated, will, it is claimed, fulfil the functions of a good ventilator. The follow ing description of it is given in the Amei iran Atjriculturkt :—: — "The nicies arc of timber, twenty-six inches long, and one foot wide at the broad end, tapering to one inch wide at the other end. The wider ends arc cut to a segment as hliown in the engraving. Quarter-inch holes are bored in the edge of one of these boards. A .sash eighteen by twenty-six

inches, with four lights of gla^s, is &creYtecl to the fiont edges ot the boards. The whole is then hung in place by a pair of wrought iron butts, screwed to the lowev side of the sash and to aboard lirmly lulled to the inside of the stable, in the reai of a stall. A Hat piece of iron, with a quartei-in'jh hole or a stout screw eye is fastened into the stable Mall directly o\er one of the f^ide boards. Through this an iron pin, a, is thrust into a hole in the edge of the side board, to hold the \entilator at any decree! an^le. When open, a» in the ent sjr.iving, a curron t ot air is admitted, in the direction indicated by the curved arrow, ventilating the stable without exposing the horse to a direct draught. "'

Tins \\Mgon jack, which is simply mado, almost entiicly of wood, can be made by any ingenious settler. The upright part is n plank or board, three feet loner, to which a diagonal brace is liunly nailed, and sawed off^o as to k-a\e the lower end level with that of the upiighl. The horizontal lever a four feet long 1 , notched on tlie ujipei edge
