The accompanying illustration shows a midden stead 10 ft. long and 7 ft. wide, with 9-in. brick walls, 2 ft. 6 in. high round three sides. The end is left open, so that a cart can be backed in, and the roof is kept high enough for the same purpose. The floor should be covered with flags laid with a fall, as shown, and in the end wall a perforated grating allows the liquid to run through a pipe into the pit. The pit is oft. deep, 6 ft. long, and 4 ft. wide. It may be covered over with 4-in. flagstones. The sides are of 9-in. brickwork, cement rendered, and the bottom is of cement concrete laid with a fall to one corner, so as to make a sump for a chain-pump, which should be fixed high enough to pump the liquid into a tank cart for carrying to a distance.
