 Ojiidtn. A'/roii. [.Iain: J-Zrpl. f,aiiihi:'\, .} {I!)0S), Xn. i*, jiji. B4I, 243). — A brief survey 

 of the activity of the Russian forestry administration for this i)e,riod. 



A primer of forestry, (J. I'lNCiiox {V. S. Dcpt. Agr., Fanners' Ihd. 17-i, pp. 47, 

 JUjx. .?J). — This bulletin is a popularization of a former ])ublication of the Division of 

 Forestry (E. H. R., 11, p. <S5ri). The text has been revised to some extent and many 

 \\v\\ illustrations i)rovided. It is l)elieved that the new bulletin will i)rove more 

 useful for general distribution than the previous ]>ublication. 



SEEDS— WEEDS. 



The influence of sterilized soil on seed germination, (i. E. Stone and R. E. 

 Smith {Massachusetts Sta. Rpt. 1902, pp. 4O-42). — The authors have observed for some 

 time in their study on the influence of sterilized soil on various plant' diseases that 

 the seedlings and subsequent growth of plants germinated in sterilized soil were more 

 vigorous than those in soil not so treated. In the present report they give a brief 

 account of experiments to determine the effect of sterilization of the soil on the germi- 

 nation of seed. Old seed of low germinating capacity were selected for the purpose 

 of the investigation, and results of the tests with radish, tomato, cucumber, lettuce, 

 onion, mustard, turnip, and clover seed are given. Two hundred seeds of each kind 

 were used in each experiment, in some instances the experiment being repeated 3 

 times. While the results can not be considered as conclusive, the preliminary 

 experiment indicates that the germination of lettuce, cucumber, melons, tobacco, etc., 

 is favored in sterilized soil. 



Experiments in the germination of corn, B. I). Halsied and J. A. Kelsey 

 {Neir Jerseij Stas. Rpt. 1902, pp. 409-412, pi. 1) . — The results of a numl)er of experi- 

 ments on the germination of corn are given in which an attempt was made to deter- 

 mine some of the factors which might contribute to the production of an)ino <jr white 

 seedlings. Tlie seed was germinated in the presence of as little moisture as ])ossil)le, 

 and was taken from large and small ears for comparison, from different rows in the 

 ear, from different parts of the ear, from stalks which bore more than 1 ear, and 

 from grains produced by close and cross pollination. The germination tests did not 

 give sufficiently marked differences to warrant any conclusion, but it was determined 

 that there was apjjarently some relation between close fertilization and the produc- 

 tion of albino seedlings, the albinos being most a])undant in seedlings grown from 

 ears of corn which had been close fertilized. 



On the behavior of mutilated seedlings, B. D. Halsted and J. A. Kelsey 

 {Xew Jerseij Stds. Rj)t. 1902, pp. 412-414, pi- 1)- — This is an abstract of a pajjer pre- 

 sented before the Society for Plant Morphology and Physiology January 1, 1902, and 

 subsequently published (E. S. R., 14, p. 11). 



Tests of the vitality of seeds, 1901-2, W. T. Ellis {Canada Expi. Farms Rpts. 

 1902, j)p. 45, -^6'). — A report is given of tests of 1,830 samjjles of seed grain and other 

 seeds which were tested during the season of 1901-2. More than 95 per cent of all 

 the samples were wheat, barley, oats, and peas. A tabular statement is given show- 

 ing the relative value of the different lots, and additional tables are given in which 

 results of seed tests carried on in different provinces are shown. 



Seed testing', J. S. Remincitox {Reprint from Jour. Roij. La)iras]iire Acjr. Soc. 1908, 

 pp. S). — A discussion is given of the methods of seed tt'sting, together with results 

 of some investigations, and a table which shows the purity, germination, and actual
