When the trough is full, the buoy rises and raises the lever so as to shut off the water entirely.

At every sip the animal takes, the buoy descends and lets on again, to a drop, a quantity equal to that abstracted from the inside compartment.

Thus the trough is always kept full of pure water, without losing a drop of it through a waste-pipe or overflow.
Where a great herd of cattle and a drove of horses have to be supplied from a deep well, as in the case of Mr.Jonas, at Chrishall Grange, this buoy-cock must save a great amount of labor.
I saw also here in perfection that garden allotment system which is now coming widely into vogue in England, not only adjoining large towns like Birmingham, but around small villages in the rural districts.

It is well worthy of being introduced in New England and other states, where it would work equally well in various lines of influence.

A landowner divides up a field into allotments, each generally containing a rood, and lets them to the mechanics, tradespeople and agricultural laborers of the town or village, who have no gardens of their own for the growth of vegetables.
