FORESTRY AND IRRIGATION 



583 



the Feather and the Sacramento from 

 the point of diversion southward, an 

 area of 700 square miles. It, too. is 

 built by private capital. 



The development of these great ir- 

 rigation systems is worthy of note, 

 both on account of the magnitude of 

 the enterprises themselves and because 

 of the conditions in the territory cov- 

 ered. The Sacramento Valley has an 

 annual rainfall of from fifteen to thir- 

 ty inches, and is far from being an arid 

 or even semi-arid region, notwith- 

 standing the dry summers which pre- 

 vail in California. The lands that will 



be watered by these canals have for 

 half a century produced crops. Wheat, 

 barley, vegetables, and fruits are 

 grown. Some of the largest orchards 

 in California are here, as well as 

 some of the largest grain ranches in 

 the world. 



One of the first effects of the intro- 

 duction of irrigation on a large scale 

 will be to induce the subdivision of 

 these great grain ranches into small 

 farms and the transformation of a 

 grain country, but sparsely inhabited, 

 into a land of diversified crops and 

 manv homes. 



RECENT PUBLICATIONS 



"Boundaries of the United States and of 

 the Several States and Territories." By 

 Henry Gannett. Third Edition, Bulletin 

 No. 226, Series F, U. S. Geological Survey. 

 '45 pp., 54 plates, including maps, charts, and 

 diagrams. Washington, Government Print- 

 ing Office. 1904. 



In addition to the value of such a pub- 

 lication as this in the way of defining geo- 

 praphically the boundaries of the United 

 States, and of all States and Territories, 

 there is an added value in the history of 

 events which led to changes in territory. 

 Treaties, charters, and statutes which have 

 had bearing on boundary lines, are cited, 

 and interesting historical changes reviewed. 

 It is a very handy history, chronicling the 

 territorial development of the United States, 

 and furnishes the historical student with a 

 classified list of treaties and charters which 

 have led to the accession of territory. The 

 work was first published in 1885; a second 

 edition, much enlarged, was issued in 1900; 

 and the demand has been such as to warrant 

 the publication of this third edition. 



"Economic Resources of the Northern 

 Black Hills." By J. D. Irving, with contri- 

 butions by S. F. Emmons and T. A. Jagger, 

 Jr. Professional paper No. 26, I S. Geo- 

 ' logical Survey. 222 pp., 20 plates, includ- 

 ing maps. Washington, Government Print- 

 ing Office, 1904. 



Two parts are included in this publica- 

 tion, a general geological review of the 



region, comprising the first and introduc- 

 tory part, and followed by a complete re- 

 view of the mining geology. The report 

 should be of considerable value to engineers 

 and miners, as offering an authoritative 

 compilation of the region's mineral resourc- 

 es, with maps indicating the distribution of 

 ores, and charts illustrating analyses of ore- 

 bearing rocks, with descriptions of specified 

 and sample regions, the whole forming a 

 great mass of valuable data to the engineer, 

 geologist, or expert. 



"Twelfth Annual Report of the Bureau 

 of Animal Industry for 1903." 618 pp., il- 

 lustrated. Washington, Government Print- 

 ing Office, 1904. 



The Bureau of Animal Industry have di- 

 rected an active campaign against impure 

 meat-food, through inspection of annual 

 food products, investigation into proper 

 methods of raising stock, prevention of dis- 

 eases of the same, methods for proper 

 manufacture of foodstuffs allied to stock. 

 compilation of statistics on the above 

 subjects and their relation to sim- 

 ilar industrial lines in foreign coun- 

 tries, and in the broad field of investiga- 

 tion, research, and administration. Then- 

 twelfth annual report is a digest ni the 

 work accomplished in the fiscal year just 

 past, and there is a widely diversified lot oi 

 interesting articles, and a mass ot data con- 

 cerning its work.
