Mushrooms may be grown in pots, boxes, or hampers. - Each box may be three feet long, one and a half broad, and seven inches in depth. Let each box be half filled with horse-dung from the stables (the fresher the better, and if wet to be dried for three or lour days before it is put into the boxes); the dung is to be well beat down in the box. After the second or third day, if any heat hat arisen amongst the dung, break each spawn brick into three parts as equally as possible, then lay the pieces about four inches apart upon the surface of the dung in the box; here they are to lie for six days, when it will probably be found that the side of the spawn next to the dung has begun to run in the dung below; then add one and a half inch more of fresh dung on the top of the spawn in the box, and beat it down as formerly. In the course of a fortnight, when you find that the spawn has run through the dung, the box will be ready to receive the mould on the top; this mould must be two and a half inches deep, well beat down, and the surface made quite even. In the space of five or six weeks the mushrooms will begin to come up; if then the mould seems dry, give a gentle water ing with lukewarm water. The box will continue to produce from six weeks to two months, if duly attended to by giving a little water when dry, for they need neither light nor free air. If cut as button mushrooms, each box will yield from twenty-four to forty eight pints, according to the season and other circumstances. They may be kept in dry dark cellars, or any other places where the frost will not reach them. And by preparing, in succession of boxes, mushrooms may be had all the year through. They may be grown without the dung, and be of a finer flavour. Take a little straw, and lay it carefully in the bottom of the mushroom-box, about an inch thick, or rather more. Then take some of the spawn bricks and break them down - each brick into about ten pieces, and lay the fragments on the straw, as close to each other as they will lie. Cover them up with mould three and a half inches deep, and well pressed down. When the surface appears dry, give a little tepid water, as directed for the last way of raising them; but this method needs about double the quantity of water that the former does, owing to having no moisture in the bottom, while the other has the dung. The mushrooms will begin to start in a month or five weeks, sometimes sooner, sometimes later, according to the heat of the place where the boxes are situated. The spawn bricks may be obtained from seedsmen, or be collected from meadows.
