The Gardener's Chronicle (Gr. Britain), gives the following in- 

 teresting statistics showing the number of plants that may be grown 

 from a bushel of seed: "Horse Chestnut, 2500; Oak, 6000; Spanish 

 Chestnut, about 3000; Walnut, 5000; Norway Maple, 12,000; 

 Sycamore, about 12,000; Ash, 14,000; Beech, 10,000; Elm, 1000; 

 Birch, fully 16,000; Holly, 17,000; Scotch Fir, 9000. From one 

 pound of seed: Spruce Fir, about 9000; Larch, 3000; the Cluster 

 Pine, Silver Fir and some others, about 500 upward." 



Jenkins in the "Art of Propagation" gives excellent notes on the 

 practice of raising trees from seed. He writes: "As a general rule 

 forest tree, and many other seeds, should be planted in the Fall 

 soon after they ripen, or, if reserved for Spring planting, should be 

 mixed with earth, moss, leaves, or other material, to prevent 

 drying; imitating, in a measure, the conditions and protection pro- 

 vided in nature. 



For seeds of the nut-bearing tree class such as the Oak, Chestnut, 

 Hickory, black and white Walnut, the open field, if of mellow, rich 

 soil, makes a good and sufficient seed bed.

After the ground is thoroughly cultivated, mark out with a plow 

 as for Corn or Potatoes, planting the seeds closely in the light fur- 

 rows or drills.
