FORESTRY AND IRRIGATION

koosa and Rhinelander there are nine 

 excellent water powers with good lo- 

 cations for dam sites that have not yet 

 been developed. The fall of these 

 rapids vary from 20 to 90.5 feet, with 

 an approximate average of 31 feet for 

 the nine. 



Black River, between a point near 

 Neillsville and Black River Falls, a 

 distance of about 40 miles, has a total 

 fall of 337 feet, a fall of about 9 feet 

 per mile. This fall is concentrated 

 into rapids where heads from 24 to 

 85 feet can be developed. 



On the Chippewa River, and its 

 main tributary, the Flambeau, are 

 likewise many excellent opportunities 

 for power development. There are 15 

 well known locations above Eau 

 Claire, none of which have been util- 

 ized. These rapids and falls vary in 

 developable heads from 14 to 55 feet, 

 the average for the 15 sites being 

 about 31 feet. 



Sufficient information concerning 

 the St. Croix River profile has been 

 acquired to make it certain that it has 

 many very valuable water power sites. 

 The' St. "Croix Rapids at Taylor's 

 Falls contain 55 feet fall in six miles, 



nearly all of which can be economically 

 developed. There are several other 

 well known rapids above this point 

 that will eventually be developed as 

 the surrounding country is better set- 

 tled. 



The mean and minimum discharge 

 of these streams is so large as to in- 

 sure a reliable water supply at the va- 

 rious rapids mentioned. For the past 

 three years the U. S. Geological Sur- 

 vey has been doing systematic work in 

 the line of gaging of these streams 

 and their tributaries, and a consider- 

 able extension of this work will be 

 made this summer. 



The many tributaries of these 

 streams abound more copiously in 

 falls and rapids than do their parent 

 rivers. A like condition prevails on 

 the short and less pretentious streams 

 of the Lake Superior drainage. Not 

 only are the lower sites greater in 

 number on these minor streams, but 

 greater in height and fall. While 

 the discharges are comparatively 

 small, they are fairly constant. These 

 conditions offer an excellent and re- 

 liable opportunity for investments of 

 small capitalization.

Bulletin of the Iowa State College of Agri- 

 culture and the Mechanic Arts. Compen- 

 dium Number, December, 1904. Vol. Ill 

 No. I. Ames, Iowa, 1904. Pp. 80. 

 Of a high typographical standard, and 

 with numerous excellent half-tone illustra- 

 tions and interesting reading matter, this 

 Bulletin of the Iowa State College of Agri- 

 culture and the Mechanic Arts certainly 

 should serve to attract students, and further 

 than a mere catalogue of the school, pre- 

 sents in an attractive manner the diversified 

 charms of campus, dormitory, lecture room, 

 foundry, machine ship, 'and college activities. 



Johnson's Guide to the Government Land 

 of the United States. Wm. H. John- 

 son publisher, Springfield Mo. Pp. 152, 

 illustrated. 1905. 



This volume was published with an idea 

 of giving the best possible information con- 

 cerning the public lands where entries may 

 be made, character of land, how to make 

 entries, and with synopses of homestead, 



desert, timber, mining and irrigation laws. 

 The book has two grand divisions : First, 

 "The Land," in which is described by states, 

 all land open to entry ; and, second, "The 

 Law," in which all legislation, national or 

 state, is discussed, also by states. To the 

 homeseeker the volume should prove a 

 boon, and the information given is substan- 

 tially correct. Numerous half-tone illus- 

 trations embellish the book and amplify 

 upon the reading matter.
