. Bulletin (Pennsylvania Department of Forests and Waters), no. 46-50. Forests and forestry. Freshly sown seed is pressed into the soil by means of a large heavy roller 21 cliiof aclvantaj^e in the use of sand lies in its freedom from weed seed and the spores of fungi. However, this is to be remembered: nature, through millions of years, evolved the very best methods. At the Clearfield nursery an effort is made to duplicate those methods so far as possible. Hence woods soil or some similar material, such as well-rotted compost, is preferred for covering seed. For spreading til is material, wire with three meshes to the inch is suitable for use in a hand sifter. Sand should be applied through a wire with four meshes to the inch. THE BEDS ARE MULCHED WITH STRAW After the seed is covered, the beds are mulched with about an inch of straw that is free from weed seed. Leaves, bracken fern, or pine needles can be used if available. At the Clearfield nursery a spe- cially-constructed cart is employed for mulching. Its wide-set wheels straddle the bed. The back of the cart is open. Two men, one on either side of the bed, draw the cart by its long cross-handle, and a worker back of the cart pulls the straw out behind as the cart moves slowly along. When the mulch has been spread, cross-strips and shades are laid on it to hold it in place. The pur- pose of this mulch is, of course, to insure both good shade, moisture conditions, and to keep the soil loose and prevent it from baking, so the seed can sprout. If the season is dry, it is advisable to s[)rinkle the beds either before seeding or after applying the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Pennsylvania.
