mations in shaping the topography is pointed out. The mathe- 

 matical laws governing the transporting and eroding powers of 

 water are set forth and their application shown very clearly under 

 the existing conditions. 



Based on the conditions as found the writer recommends that in 

 future regulations of grazing a reduction of 2,000 head of cattle 

 and 27,000 head of sheep should be made in the number allotted 

 to graze on the Forest at the time the examination was made. 

 The reasons for this reduction seem to be well stated and the 

 whole dtescrip^ion indicates that their foundation is no less 

 secure. 



The bulletin is provided with an admirable summary which 

 states the case in a nutshell. Another feature is the photographs 

 which picture typical portions of the Forest and range clearly. 

 One, in particular, is a most forceful illustration of the relation 

 of the vegetation cover to erosion. 



Altogether this bulletin is a good write-up of the observed facts, 

 the conditions, and the statements of various Forest users in 

 regard to the influence of forest cover as it affects water con- 

 servation and floods. The only thing regretted is the absence of 

 measurements and figures showing the rainfall in various parts 

 of the watershed and the resultant flood discharge through a 

 period of years. This, of course, was obviously impossible be- 

 cause of the short time and the condition under which the report 

 was prepared. Future detailed measurements will doubtlessly be 

 made and it would seem could only reinforce the conclusions 

 drawn in this publication.

Utilisation of Osage Orange. By Hu Maxwell of the U. S.

The natural range of Osage Orange (Toxylon pomifernm Raf.) 

 embraced little more than ten thousand square miles in north- 

 eastern Texas and southern Oklahoma, and probably half of that 

 area produced no trees of commercial size. From this restricted 

 region it has been artificially propagated over most of the United 

 States, chiefly for hedges and ornamental planting.
