Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 533. Picturesque old hemlock spruces. the other hand, for the first three months, until they have made their crown bud, need to be either kept well watered or else protected against the drying effects of sun and wind by shading, for which purpose lath screens are best. These latter must be lifted for airing after the sun is gone, especially in muggy weather, to avoid " damp- ; For wintering, a covering with conifer branches or very clean meadow hay is advisable (the latter is apt to bring in weeds). For growing small quantities, the use of boxes, as described by Jackson Dawson, of the Arnold Arbore- tum, in Proceedings of the Massachusetts Horticultural Society, is highly commendable. In well drained boxes, sow the seed soon after gathering, pile four or five deep in a pit or sheltered place, cover with boards, and when cold weather comes, cover up with leaves or hay. About the middle of April, move them into a place where they get the early morning sun. Keep the seedlings well watered and free from weeds, and shaded as described. Winter the seedlings in same manner as the seed-boxes, well covered up. They are ready for transplanting next spring, when they are making their first or second set of rough leaves. Since pine and spruce seedlings take about 7 to 10 pounds of phosphoric acid, 10 to 20 pounds of potash and 15 to 30 pounds of lime, besides 20 pounds of ni- trogen, per acre from the soil, for continuously used nurseries the addition of mineral materials in the shape of bone-meal and wood-ashes may become desirable. A large number of seedlings may be grown in a small space; thus 30,000 Norway spruce may be grown on a square rod, requiring about 2 pounds of se
