AMERICAN FORESTRY 



Trail and Tree Top, by Allen Chaffee, illus- 

 trated with drawings by Peter J. Da Ru, 

 Milton Bradley Company, Springfield, 

 Massachusetts, Price $1.25. 

 In the introduction to this charming book, 

 just from the press, we find that it holds, in 

 true-to-nature form, some of the comic, 

 daring or pathetic exploits of Mammy Cot- 

 tontail, Jimmy Crow and brave grumpy old 

 Fatty Chuck, for whom Frisky Fox and the 

 others kept things so lively. And here too, 

 is the Boy from the Valley Farm, who knew 

 just what to do in some of the emergencies 

 that befell his furred and feathered friends. 

 Trail and Tree Top will be welcomed by 

 all little folk who love the woods-people, 

 for while there are a few big words for the 

 while there are a few big words for the 

 grown-ups, these are all explained for the 

 younger readers. 



"Going Afoot," by Bayard H. Christy, 

 fiom the Association Press, of New York, 

 will be welcomed by the clan of the 

 strenuous and the lovers of life out of 

 doors. They will gain from this little book 

 a new appreciation of the joys of the road 

 and will find it full of practical and helpful 

 suggestions on when, how and where to 

 walk. Trampers will read with much 

 interest the accounts of famous walking 

 clubs in America and directions for the or- 

 ganization and conduct of such clubs. 



LARGEST SAWS IN THE WORLD 



^7 HEN it was suggested that Henry 

 Disston and Sons make some circular 

 saws 108 inches in diameter to be used in 

 cutting shingle bolts, most people laughed 

 and thought the idea crazy. The strain 

 would be too great, no mandrel could hold, 

 a saw with a surface so large could not 

 run straight and true. But even as Mar- 

 coni accomplished his idea of the wireless 

 telegraph after all the world mocked, so 

 has the Disston firm done what seemed 

 impossible. On April 10, 1920, two circu- 

 lar saws, 108 inches in diameter, made in 

 the Disston plant in Philadelphia, began 

 their first run in the Coats Shingle Mill at 

 Hoquiam, Washington, and they ran per- 

 fectly. Special machinery was necessary 

 to carry them. The power turned on, they 

 began to run slowly, then as the speed grew 

 the hum increased until it sounded like 

 the noise of a swarm of bees. The serrated 

 edge, traveling at a speed of 130 miles an 

 hour, cut through big Coast logs with an 

 ease and rapidity that astonished ex- 

 perienced mill men. With an ordinary 

 saw the shingle weavers frequently had 

 to wait for bolts to accumulate, with the 

 installation of these saws the crews in the 

 cutting and packing departments were fair- 

 ly swamped.

10 hours ditch blasting 



worth 500 bushels of wheat 



Mr. V. S. Darling:, Auburn, Maine, 

 secured that result. Ten hours of ditch 

 blasting added $1000 to the value of his 

 farm. Mr. Darling writes: 



"On October 15th, with Atlas Powder, we 

 blasted a 600-foot ditch 4 feet wide by 2y 

 feet deep in about five hours. We got a 

 perfect ditch. I have about 600 feet more 

 to blast and when this is finished the job 

 will be worth at least S1000 to me. " 



Our Book, "Better Farming with Atlas 

 Farm Powder," will show you how to 

 blast ditches, remove stumps and do other 

 farm blasting even though you be inex- 

 perienced. Write for a copy today.

FORESTS AND IRRIGATION 



A N excellent illustration of the relation- 

 ship that exists between forested areas 

 and the irrigation problem is the follow- 

 ing: 



Tip a table to the angle of 45 degrees 

 ant! cover its surface with sponges to cor- 

 respond with the layer of decomposed vege- 

 table matter in a forest. Pour water over 

 the table and a large proportion will be 

 retained in the sponges to ooze out gradu- 

 ally. Remove the sponges and repeat the 

 process of pouring water over the table. 

 Of course the water will immediately seek 

 the lowest level. Forests on mountain 

 slopes have the same effect in retaining 

 water that the sponges had. Water from 

 winter storms held back by the forest's 

 decomposed vegetable matter, enters the 

 ground, and oozes out gradually later in 

 the year. 



From the foregoing, the necessity of 

 protecting our forested areas from fire 

 and the necessity of having mountain 

 slopes, not valuable for agriculture, covered 

 with forest trees is readily understood.
