 (Introduction to biology.) ^th ed. B. G. Teubner: Leipzig and Berlin, 1919.] Forstwiss. 

 Centralbl. 43: 73-74. 1921. — A most excellent and well illustrated textbook for the higher 

 schools, as well as for self-instruction. The physiological side has been emphasized more than 

 in previous editions, and chapters on heredity, genetics, and other subjects have been added. —

1215. Wells, B. W. A method of teaching the evolution of the land plants. Torreya 

 21: 45-47. 1 pi. 1921. — The comparative method constitutes the only vital approach to 

 the story of plant evolution. The types must be brought together so that they can be automati- 

 cally compared. The plate, which is the work of a freshman student, illustrates how this 

 may be done graphically. The life cycles are drawn concentrically, the lowest in the center. 

 The significant stages are marked out by radii. Each circle is filled in by the student as he 

 finishes his study of the type. All the evolutionary changes in a given structure are seen 

 by following its radius outward. — J. C. Nelson.

1216. Anonymous. Das Reichsforstgesetz. [The forest law for the German Empire.] 

 Forstwiss. Centralbl. 43: 37-39. 1921. — This is the text of the proposed Imperial forest law 

 formulated by the Imperial Forestry Council (Reichsforstwirtschaftsrat) in September, 1920. 

 It is designed to make the practice of forestry compulsory on all forest lands in the empire, re- 

 gardless of ownership. Administration of the laws, as well as the details of the laws them- 

 selves, are left for the most part to the individual states. — W. N. Sparhawk. 



1217. Anonymous. Forestry in relation to agriculture. Agric. News [Barbados] 20: 34. 

 1921. — The author discusses the differences between forestry and agriculture, pointing out 

 where the two overlap. Forestry in tropical America, now and for some time to come, should 

 proceed only on lines of organization, survey, and judicious cutting, and to a lesser degree 

 along those of reafforestation, mensuration, high finance, and working plans. — J. S. Dash.

 comprehensive report of the Director for the calendar year 1919 is presented, setting forth

 caused a damage of 21,446 kroner. The personnel consists of 3 inspectors, 2 assessors, 24 

 assistants and 504 rangers or "Vogtere." The service planted 552,977 trees. — J. A. Larsen.
