BOOK REVIEWS 



Manual of Tree Diseases, by How- 

 ard Rankin. The Macmillan Company, 

 New York City. Price $2.50. This 

 volume treats of the diseases of the 

 more common trees of the United 

 States. The discussions are grouped 

 into chapters under the common name 

 of the tree affected and the chapters 

 are in alphabetical order, which facili- 

 tates the use of the book for reference. 

 In one general chapter are included 

 discussions of the diseases common to 

 all kinds of trees, such as samping 

 off of seedlings, temperature injuries 

 to leaves and woody parts, smoke and 

 gas injuries, woodrots, etc. The 

 species of trees affected, their geo- 

 graphic distribution, the symptoms of 

 the different diseases and their par- 

 ticular destructive qualities are pre- 

 sented fully and clearly. The casual 

 agent of the disease is briefly de- 

 scribed and when it is caused by a 

 parasite, some descriptive details of 

 the life history of the parasite are 

 given, with valuable suggestions as to 

 control, and tree surgery is given 

 separate and special treatment. 



Our National Forests, by Richard H. D. 

 Boerker. The Macmillan Company, 

 New York City. Price $2.50. Dr. 

 Richard H. Douai Boerker. who has 

 for more than ten years been in close 

 contact with the federal forestry 

 movement, in his new book. "Our 

 National Forests," covers the subject 

 exhaustively and, at the same time, in 

 a most readable manner. The book is 

 divided into four parts : I. The Crea- 

 tion and Organization of the National 

 Forests. II. The administration of the 

 National Forests. III. The protection 

 of the National Forests. IV. The Sale 

 and Rental of National Forest Re- 

 sources. 



That the disappearance of forests 

 means the ultimate disappearance of 

 everything in civilization that is worth 

 while may seem like a broad statement 

 but that it is a truly accurate one is 

 proved conclusively in Dr. Boerker's 

 interesting and stimulating study. Ac- 

 cording to the author of this scholarly 

 survey, the sins committed against a 

 nation's forests are visited again, and 

 swiftly and surely, upon the inhabi- 

 tants thereof. The punishment may 

 take the form of timber famine, or it 

 may express itself in failure of water 

 power. Floods are another terrible 

 form of punishment visited upon those 

 who neglect and misuse forest re- 

 sources. Following closely in the 

 wake of floods come the coverint: of 

 fertile bottom-lands with gravel, bowl- 

 ders and debris ruining the land be- 

 yond redemption. Erosion of soil is 

 another inevitable consequence of for- 



est abuse and neglect. Last, but not 

 least, the drying up of springs and the 

 transition from a luxurious, well- 

 watered country into a veritable desert 

 is the inevitable result of forest misuse. 

 Solemnly biblical, Cassandra-like 

 and out-of-date as all this may sound. 

 it is, none the less, a very present and 

 real danger, a following of cause by 

 effect, the visiting upon the negligent, 

 the prodigal and the unwary of swift 

 and terrible penalties in the present 

 and future as in the dim past. 



BURN WOOD SAVE COAL 



WOOD is to play a conspicuous part 

 in the nation's work again this 

 winter, according to an announce- 

 ment of the United States Forest Service. 

 An appeal has been issued to farmers who 

 own woodlands and people in cities, towns 

 and villages who can purchase wood from 

 nearby farms to help in the coming win- 

 ter as last winter to relieve the demand 

 for coal and the strain on railway capacity 

 by burning wood in place of coal. And 

 responses to date indicate that the Ameri- 

 can people who can will do this very thing. 



It is not expected that the substitution 

 of wood for coal will be universal, but it 

 is declared that for heating many kinds of 

 buildings wood is the more convenient and 

 cheaper fuel. This is particularly true in 

 the case of churches, halls and other build- 

 ings for which heat is required only oc- 

 casionally, but then is wanted in large 

 volume on short notice. 



The most common method of making 

 cordwood is to cut the trees into four-foot 

 lengths with an ax and split the larger 

 pieces, which are then piled in a standard 

 cord, eight feet long, four feet high and 

 four feet wide. The contents are 128 cubic 

 feet, of which 70 per cent is wood and 30 

 per cent air. Wood cut four feet long can 

 be sold to brickyards, limekilns, metal - 

 working plants and other industries, but 

 is too large for household uses. 



Another method, and one better adapted 

 for old growth hardwoods, which are diffi- 

 cult to split, is to saw the tree into logs 

 of convenient lengths, say from ten to 

 fifteen feet. These are "snaked" out to the 

 edge of the woodland and there sawed into 

 lengths and split into sizes propc - for the 

 stove or furnace. The sawing is usually 

 done by machine, driven either by gasoline 

 or by electricity. The wood is piled four 

 feet high and eight feet long, such a pile 

 being called a "stove-wood" or "running" 

 cord. 



Firewood is expected to bring a better 

 profit this year than ever before. It is a 

 much less perishable crop than many which 

 the farmer raises. When properly piled 

 the better kinds of wood will last from two 

 to three years.
