This bulletin appears to be the first attempt in grazing Hterature to 

 assemble information regarding the ecological requirements of grazing 

 plants. Information on the points enumerated above was secured over 

 a period of years, and in many cases the actual ecological requirements 

 determined through physical-factor measurements. 



As a means of comparing habitat requirements, the species are 

 grouped in 3 classes, namely, those of high moisture requirements, in 

 habiting saturated soils, such as open marshes, wide meadows, and 

 bogs; those of medium moisture requirements, inhabiting heavy soils, 

 which are saturated during the early period of the season, but later 

 contain a medium amount of moisture ; and those of low moisture re- 

 quirements, growing on well-drained soils, open glades, and in exposed 

 situations. It was found that about three-fourths of the most valuable 

 species are dry-land plants and more or less drought-resisting.

 Province of New Brunszmck for the Year Ended October ?/, ipi/. 

 Hon. E. A. Smith, Frederickton, N. B. 1918. Pp. 206. 



It is a matter of gratification to note from this first report of a new 

 political administration how entirely and whole-heartedly the Province 

 of New Brunswick is committed to its newly inaugurated forest policy. 



The new Minister of Lands and Mines, Hon. E. A. Smith, with most 

 appreciative words for the technical men. not only approves what his 

 predecessors have done in starting a forest survey and forest ser\'ice, 

 but proposes to increase the organization to a fully equipped depart- 

 ment, with initial appropriation of $100,000. handing over to it at least 

 certain features of the timber-land administration. When it is consid- 

 ered that the whole income from the crown timber lands docs not exceed 

 $450,000, this is a generous beginning, especially as, owing to war con- 

 ditions, tlu' oiitj)Ut has bccTi declining and a greatly reduced cut is ex-
