transplants after two years in bed. They are planted in about 3 by 5 

 feet spacing in furrows and do not need replacement unless more than 

 25 per cent fail. In five years such a plantation is established, and in 

 ten years the oak and chestnut need to be freed from the birch, which 

 is then fit for broom handles. 



For pine plantations the author mixes the two pines, because the 

 more rapid maritima is not surely frost-proof ; hence in case of its fail- 

 ure the silvestris will at least survive. Although even sowings in fur- 

 rows and spots have been sufficiently successful, the author favors for 

 the highly siliceous sand and gravel soils planting with ball, using a 

 circular spade. For this purpose the planting stock must, of course, 

 be grown on a sufficiently compact (clay or humous) soil, so as to keep 

 the ball from breaking down in transportation. This is done on strips 

 I yard wide and 1.5 yards left blank between, on which the surface 

 debris of the prepared strips (by hoe) may be raked. He uses as much 

 as 60 pounds per acre of Scotch pine seed and double the quantity for 

 the maritima. On better soils this could be reduced. From such sow- 

 ing 60,000 silvestris and 80,000 maritima plants can be secured, besides 

 leaving enough to reforest the strip. Almost the entire output of the 

 maritima is utilizable, while in the silvestris selection is necessary. The 

 age at which the plants may be transplanted ranges from two years to 

 four years ; exceptionally silvestris may be used up to six years ; if 

 planted in mixture, four-year-old Scotch with two-year-old maritima 

 should be used. They are then set out, spaced i by 1.5 yards, which 

 makes complete crown cover in about 12 years.

The appearance of a volume of 263 pages (Le 

 Black Robinier pscudacacia), by G. Vaulot, in 1914, 



Locust gives occasion to Jolyet to sing the praises of this 



to the species, especially for reforestation of the devas- 



Pront tated French and Belgian forests. Ease of prop- 



agation, cheapness of seed or plants, and high 

 germinative power, drouth resistance, rapid growth, and superior wood 

 quality combine to make the species desirable. That it is a tree of small 

 dimensions does not seem to detract from the author's appreciation. 

 Frost hardiness is, however, doubtful and is discussed at length. It is 

 admitted that the southern climate of France is more congenial to the 

 species, but the author thinks it will thrive in the north also, escaping 

 the late spring frosts by its tardy leafing and finding there warm sum-
