northern part of the southern peninsula of Michigan. The land 

 examined is included in the State forest reserve, which contains some 

 60,000 acres of White, Red, and Jack Pine stump land 



A study of the reserve was made for the purpose of suggesting a 

 plan for its proper management and for that of other similar lands in 

 the same region, and recommendations were made to the commission. 



^en^wc%.— Investigations were begun last season on the forest con- 

 ditions and resources of Kentucky, with special regard to the effects 

 of destructive lumbering and of fire on the forest and its reproduc- 

 tion. A preliminary report of progress has been made, but another 

 season's field work is required before a full report can follow. 



Ohio. — A general examination of the forest resources of Ohio was 

 begun last year to determine the location and extent of available sup- 

 plies of commercial hardwood timber. In connection with this exam- 

 ination a study was begun of the relation of the wood-consuming 

 industries of the State to existing supplies of timber. Search was 

 made also for historical and other evidence to show the effect of 

 denuding forest lands on the flow of streams. A report on the avail- 

 able tree species of the State has been submitted, together with a pre- 

 liminary account of lihe consumption and principal sources of timber 

 supply. The information in question is greatly needed to answer 

 constant inquiries concerning supplies of Oak, Hickory, and other 

 hardwoods. 



A special study was begun of the moisture content of green wood. 

 Tables have been constructed showing the percentage of water con- 

 tained in samples of the green wood of seven commercial timbers of 

 Ohio. This study will be extended and will form a basis for the deter- 

 mination of the best conditions for air-drying timber. 



Texas. — The forest resources and general forest conditions of Texas 

 were studied and a report Avhich gives an accurate survey of the gen- 

 eral and typical forest conditions of the State is nearly ready for pub- 

 lication. 



New Mexico. — An examination was made of the forests on and in 

 the region of the Sacramento Mountains. Particular attention was 

 given to the relation of grazing to the perpetuation of the forest cover, 

 and of the latter to the flow of water, which is of vital importance in 

 contiguous agricultural regions. 



Arizona. — Studies were made of the forests of Mount Graham, the 

 Santa Catalina Mountains, the Huachucas, and the Chiricahuas. A 

 portion of the forest lands of the Verde River basin was also examined, 

 likewise with special regard to their relation to local water supplies. 

 Aside from this question, the facts gathered will be of great service in 

 answering frequent inquiries concerning the commercial timber sup- 

 plies of these regions. 



South Dakota — The forest lands on and in the vicinity of Turtle 

 Mountain, Short Pine Hills, and Slim Buttes were studied and reported 

 upon for the same important purposes. 



Wyoming.— All examination of the forest lands contiguous to the 

 Yellowstone National Park was made with special reference to the. 

 grazing problem. The urgent need for protection of the local water 

 and timber supply gave this work peculiar significance. 



Montana.—A special study was begun in the Flathead Lake region 

 of the terrestrial and climatic factors which influence the distribution
