Soluble Food for Stock. 
of solution and available for the stock of all kinds drinking at tlie 
trough. My watei-troughs are Tinfortunately too shallow to allow 
the plan to bo thoroughly carried out, and the pipe conveying the 
liquid-food from the pump-trough (No. 1) to the yard-trough (No. 2) 
is too small in diameter to receive anything but pure and immixed 
water. Hence 1 have not been able to fairly try my plan ; at the 
same time I am fully satisfied of its utility. I send you a rough 
plan, not exactly of my own troughs, but such as I think they ought 
to be, and as I hope one day to make them : — 
No. 1 is the water-trough nearest the pump, into which the meal 
should be first received ; it should always stand half-full of water. 
No. 2. Farmyard-trough, containing the meal and water, at which 
young and old stock drink daily. 
No. 3. Pump. 
No. 4. Lead pipe, conveying the mixture to farmyard-trough. 
No. 5. Pump water-pipe flowing rapidly into No. 1, and dis- 
turbing the mixture. 
No. 6. Water level in No. 1 trough. 
It is important the troughs should be a good size— the larger the 
better — and fully three feet deep; but this must depend on the 
quantity of water required. The trough (No. 2) should be placed a 
few inches higher than No. 1, to prevent the person pumping from 
letting the mixture run over and causing waste. The pipe (No. 4) 
shoTild not be less than l^j-inch bore, and protected from frost. 
This plan of preparing soluble food for stock is attended vidth the 
additional labour only of putting the meal into No. 1. All the rest 
is self-acting, the water being set in motion by its own gravity. 
Some experience is necessary to determine the quantity of meal used : 
perhaps half-a-pound per head per day would be a fair allowance. 
I am, Sir, your obedient servant, 
J. J. EOWLEY.
