Spawning on the Surface.
If you have plenty of spawn, this is a good method to have a forward and plentiful crop, as the spawn may be laid pretty close all over the surface, and earthed over two inches thick, as follows.
Begin the spawning along the bottom first, as in the other method, quite down at the lower edge of the bed; placing the pieces of spawn flat-ways upon the surface of the dung, beside one another, either closer or wider asunder, according to the plenty, proceeding with a regular layer all along, a foot wide, up the side of the bed, earthing this over two inches; then another layer of spawn higher up the bed, and earth it as the other, and so on till finished, laying the small crumbs of spawn remaining at last upon the top of the bed, earthing it over as before directed, smoothing the whole with the back of the spade; and place some sticks down to discover the working of the bed and temperature of the heat, as in the former method.
The covering of litter or straw must also be applied in due time, when you perceive no appearance of after-heat, observing the same precautions and method as already advised in the preceding article of Spawning in the Dung.
