Description of a Feeding House for Cattle erected by Thomas Johnes, Esq. at Hafod.

The Engraving represents an elevation of the building be- ing one of the ends thereof extending from A to F, 34 feet, divided by a wall B, into two parts by a shelving roof, the part from A to B is intended merely as a receptacle for manure, the other part from B to F is properly the feeding house. The length of the whole building is 50 feet. The heighth from B to H 14 feet, from Ato G 7: feet, from F to I 6 feet. The width of the feeding house from B to F is 19 feet, inside measure, the stalls are each 12 feet long by 4 feet two inches wide. A gang-way of near 31 feet will be at the heads and tails of the cattle leading from the doors C E. The first of which is for the egress and regress of the cattle, the other for furnishing them with food. Similar doors are also at the op- posite ends of the building.

Running water is supplied to the cattle in troughs when- ever they please, and they have also mangers and racks for hay. The cattle lie upon wooden platforms perforated for the moisture to pass through. At the back of the feeding house from A to B is the covered dung pit, into which all the urine runs, and into which the dung is to be pushed through apertures in the wall B, each of which apertures is two feet square, and is between every two stalls. M is a fold- ing wood flap or window, of which there are twelve, to give light and air to each stall.

In Mr. Johnes’s feeding house, the walls B DF are built of stone, the parts N O above the door-way are made of wood, and the roof is made of larch wood by way of experiment to

“prove its durability, but it is probable that brick and slate will

in most cases answer best for the purpose.

The dung pit from A to B is about twelve feet wide, it is sunk some feet deep in the earth and extends the whole length of the building.

OBSERVATIONS OF MR. MIDDLETON’S ROTATION OF CROPS.

To the Editor of the Agricultural Magazine.

Sir, Entirely agree with your Correspondent, John Middleton, in principle, in“ th® rotation of crops,” which he recom-

mends in the last Number of your Magazine, page 323, namely, that of“ two green or rvot crops for one of corn.” For, surely it is the only way to gain any thing great and valuable from our land, to keep it up lo,if L many use the ex- pression, or, rather. above, its work. And when this is the _gase, every thing which we sow is placed almost beyond the
