The germinating bed must offer the seed a proper, constant andequal supply of heat, oxygen and moisture. The actual amount ofheat, oxygen and moisture required has not been ascertained scien-tifically. Observation in the woods is the best teacher of the condi-tions securing the largest possible germinating percentage for anygiven species. The preparation for seed-planting may extend over the entirearea to be planted; or only over certain strips which may be inter-rupted or continuous: or it may merely involve the grubbing of plotsor spots. Where the ravages of game or mice are feared, irregularworking is advisable. 43. s VLV ICll/JT i: E. A. Removing the soil covers, such as briars, Kalmia. Chinquapin, mosses, dead leaves, humus.

Incertain cases an iron rake might do. Often it i- necessary to removethe cover by tire: tire, however, produces a heavy growth of weedson fertile soil (as in Pisgah forest). B. Loosening the -oil. Jnst after logging, the -oil has enoughporosity to allow of the development of a second growth. On aban-doned fields or in prairies thorough working with the plow, oftencontinued for a number of years, may or musl precede the act ofplanting. Paragraph XII. Securing and preparing the seeds. A. European tree seeds are usually bought from reliable rival in furnishing the best seed at the lowest price, guaran
