AN IMPROVED CONSTRUCTION OP A HORSE SHOE.

ends, so as to form one piece, the middle 

 of which may be five or six inches in di- 

 ameter^ and the hole or opening at each 

 small end, the same diameter, as that of 

 the shaft, to which it is confined, so that 

 the shaft, sheet tin vessel, and puller/, all 

 turn together. 



The sheet tin vessel has holes made 

 round the periphery at its largest diameter, 

 for the seed to pass out, when each hole 

 •respectively is at the lowest position while 

 revolving; the dimensions of each hole is 

 sufficient for one large seed, or two small 

 ones, to pass at the same time, the seed 

 drop into a tube large at the upper end 

 and small at the lower end which con- 

 ducts the seed into the track, or hollow 

 formed by the wheel immediately be- 

 hind it, and are covered by a roller, which 

 turns with a gudgeon at each end, in the 

 respective feet of th-e wheel-barrow, near 

 their lower ends. The distance of the 

 holes in the sheet tin vessel asunder, 

 may be estimated at a medium between 

 t-lie extremes, at which plants are requir- 

 ed to grow. 



The extremes will of course be found, 

 by placing the endless band first at one 

 extreme end of each pulley, and tlien 

 shifting it to the other extreme end of 

 each pulley, and moving the wheel for- 

 ward, while in each of these positions. 



There is another hole or opening made 

 into the sheet tin vessel of about half an 

 inch diameter, to pass the seed into it, 

 which may after^vards be closed with a 

 cork or plug. 



The above description is deemed suffi- 

 cient, to enable any one to understand how 

 to construct a machine entirely new, or 

 to attach the parts required to an old in- 

 vention common upon almost every farm. 



DESCRIPTION OF A BUTTER POT, 



To prevent butter fro7n becoming rancid 

 in warm weather, or in hot climates. 



This is nothing more than a common 

 butter pot, but is covered with an earthen 

 cover, made of that porous kind of earth- 

 enware, which will permit water to pass 

 through it, and in the form of a dish, so 

 that this being filled with water, the water 

 percolates down the sides, and produces 

 a coolness by its constant evaporation. 



AN IMPROVED CONSTRUCTION OE A HORSE 

 SHOE. 



It is remarked that the hoof of a horse, 

 has a constant tendency to increase in cir- 

 cumference, and that when this natural 

 propensity is counteracted by the opera- 

 tion of a firm ring of iron nailed all round, 

 the least powerful part yields to the pres- 

 sure, which then falls upon the tender 

 mechanism of the frog, excites a degree 

 of inflammation, and ends in contraction; 

 to remedy this it is proposed to use a shoe 

 jointed about the middle of each side, 

 having a sunk hole near the point of the 

 heel, large enough to admit the end of a 

 screw-bar. A screw bar is then to be 

 made in two or three parts, similar to the 

 machine in daily use for preserving the 

 shape of hats, which is to be put into the 

 shoe, whenever the horse is not at work, 

 and then screwed by means of a double 

 winch, so as to keep the heels of the shoe 

 moderately extended, and this bar may 

 be entirely removed, when the horse is 

 wanted for his labours, and be again re- 

 placed when he returns to the stable. And 

 as much has been said about the mischief 

 arising from shoes remaining too long 

 upon the foot, the writer observes, that it 

 matters not how long a jointed shoe re- 

 main?, as the joints admit of the natural 

 augmentation of circumference. 



Observations. We are inclined to give 

 the preference to this, over every mode 

 formerly suggested; for preventing the 

 contraction of the foot of the horse; an 

 object deemed of much importance by the 

 Professor of the veterinary art. And it 

 appears to us that the double jointed shoe 

 alone, even without the bar, is a valuable 

 discovery, inasmuch as while the shoe re- 

 mains firmly fixed to the foot it admits of 

 all the expansion at the heel, which is 

 so essential for preserving the frog, or in- 

 ternal part of the foot from inflammation, 

 which invariably ends in contraction, or 

 closing of the clefts of llie heels. One of 

 the most prevalent, and at the same lime 

 most pernicious diseases, arises from bad 

 shoeing which contracts the foot, but this 

 could not happen if the double jointed 

 shoe was used. — Retrospect.
