1383. Weis, Fr., oo K. A. Bondorfp. Undersogelse af Skovjord under overnaerede 

 graner i Lyngby Skov. [Investigation of soil underlying over-nourished spruce in Lyngby 

 Forest.] Forst. Forsogsv. Danmark 5: 343-352. PI. 1. 1920. — A chemical examination was 

 made of the soil underlying (1) over-nourished spruce (Picea excelsa), and (2) spruce of normal 

 development. The soil of the former showed in grams per cubic meter of soil: total N 7184, 

 NaNOa 19.9, CaO 213(5, K2O 475, and P2O5 470. In the soil of the normally developed 

 spruce the amounts were: total N 1206, NaNOa 1.3, CaO 1340, K2O 654, PjOe 218. The 

 amount of nitrate in the soil of over-nourished spruce is much greater than in the other, and is 

 10 times as great as that ordinarily found in agricultural soil; it is considered the chief cause 

 of the hypertrophy. This soil was further tested in the laboratory by adding (NHj)2 SO4 

 with and without CaCOs, (NH4)2C03, KNO2 with and without carbonate, peptone, and casein 

 with and without carbonate. All tests except those with sterilized samples and those in 

 which peptone alone was added showed increases in NaNOs. The bacteria responsible for 

 the nitrification have not been found; all attempts at inoculation have failed. — J. A. Larsen.

 P. Putnam's Sons: New York and London, 1921. — The author has carefully selected 300 species 

 to represent the typical wild flower flora of Nantucket. The plants are popularly but reliably 

 described under their scientific and common names and many of them are attractively illus- 

 trated, some being depicted in color. Interesting and valuable information, not hitherto 

 of common knowledge, is recorded for a number of the species included in the work. — J. M.
