SPREADING DEVICE FOR HORSES’ HOOFS. 
Ay American device for the spreading of horses’ hoofs is ingenious, and. at 
& same time simple and inexpensive. Not only does the invention cure 
__tehess, but it is a preventive as well. It consists of a metal yoke-piece bent 
| .9 Conform to the contour of the hoof on which it is to be applied with an 
TiWardly bent hook member at each end, adapted 
4, Chgage the rear ends of the coronary band on 
© hoof of the animal. The yoke-piece shown 
* the diagram is preferably of thin steel, and 
jl In position inclines upwardly and forwardly, 
‘erreling and fitting closely on the hoof. ‘The 
pace 1s preferably employed in connection with 
+ sht shoe formed on two pieces jointed at their 
eeara ends, the shoe having at its rear ends 
Soked lips, which engage the coronary band. 
cl it is desired to spread one-quarter of the 
He only, the point of the shoe is placed at one 
te of the toe, instead of centrally, and one hook 
imber, and. the yoke-piece is made to engage with 
Notch in the shoe instead of with the coronary 
fea the full force of the expansive spring then 
U8 exerted to spread the hoof on the other side. 
© moderate pressure, constantly applied in this 
dine ‘8 adapted to gradually effect the desired 
~ q pone of the parts, relieving sensitive portions 
Promising a better circulation. 
A SIMPLE FILTER. 
i: 
Tae are several simple modes of making a filter. A very cheap, simple, and 
*ctive filter can be made by means of a common flower-pot. All that is 
site is to fillthe hole with a piece of sponge, and then place in the pot 
; “Mate layers of sand, charcoal, and small pebbles. The flower-pot thus fitted 
al May be placed in a jar, or other convenient vessel, in which the water as it 
~_!8 through can be received. ‘The effectiveness of this filter can be very much 
the wsed by having two or three flower-pots placed under each other in a stand, 
© water dripping from one to the other into a receiver below. A good filter 
“y be made by placing in a tank of impure water a vessel so arranged that a 
fino” Which it contains shall lap over the edge and dip into the water of the 
Bo - The sponge gradually sucks up and purifies the water in_ the reservoir, 
Id allows it to drop into the smaller vessel or receiver, from which it may be 
mae off by a tube. By placing a few lumps of charcoal at the bottom of the 
“Cer, filtration of the most perfect kind is effected.
