1. Preparation of the manure: It is of vital importance to let the rank steam out. When you get the manure from the stables, throw it into a round heap, and give a good watering with manure-water. Let it lie till the third day, then turn over, and give another shake up. When well sweated, which will be in three days, another turn will be necessary: it will then be ready for use.

2. Making the bed is of secondary importance. Mark out the bed 3 feet wide at bottom, and of course of whatever length you have manure for. Put the dung on in layers of 6 inches the whole length of the bed, and spread out at the rate of four shovelfuls of dry soil to every barrowful of dung; tread down by stamping on it as the work proceeds, until you get the required height; then clap the bed all over with the back of a light spade, drawing the spade downwards at every stroke, to, as it were, seal the bed. Cover up with a mat immediately, and on no account allow rain to enter. Place one stick in the middle, and one at each end. Feel the heat at least once a day; when found milk-warm, under rather than over, the bed is fit for spawning.

3. Break the spawn into pieces about the size of eggs, taking each piece in the right hand, and with the left lift the material upwards, inserting the spawn at 10 inches apart all over the bed; afterwards give it another beating, making the surface look smooth and smart.

4. This being done, set the line 9 inches from the edge of the bed, and cut the soil down inclining outwards, making a good foundation. To cover the surface of the bed, any kind of soil will do. Mine is light and rich, but just the common garden-stuff. Put 2 1/2 inches on before beating, then sprinkle over with sand to make it work clean; begin at one end, and again beat it well, always drawing the spade downwards as the stroke is delivered, till you get the whole finished. Cover up if in winter - say October - with 5 inches of straw or very dry dung, placed so that the wet cannot get in. It will now have the appearance of the roof of a hay-rick. Put a mat lengthwise over all, and reinsert the sticks, looking at them sometimes to determine whether the bed is getting too hot or over milk-warm; if so, uncover, but put the mat on this time crosswise, to keep out the wet. In this way abundance of mushrooms are grown in the open air. - Field.
