THE IRRIGATION AGE. 



being employed and there is generally a 

 wholesome condition. 



The Mammoth Mining Company, of 

 Utah, has recently struck a body of ore at 

 the 800 foot level equal to that which gave 

 the property its reputation in its palmiest 

 days. Much of it yields as much as 100 

 ounces of gold to the ton, and the silver ore 

 yields as high as 1,400 ounces. Twenty 

 new stamps are being added to the mill, 

 making a total of sixty. 



There are to be two cyanide plants con- 

 structed in the Mercur district, one by the 

 Mercur and the other by the DeLamar, 

 each with a capacity of 500 tons per day. 

 Other mills are being built in the same 

 district. The process is one calling for a 

 comparatively small outlay in the plant. 

 The ore bodies are enormous, and although 

 of low grade the cost of treatment is so 

 small as to leave a handsome margin of 

 profit. 



An article by Robert A. Kirker, pub- 

 lished in the Grand Junction, Colorado, 

 News, advocates the establishment in that 

 locality of an Oberstein lapidary factory. 

 He makes the broad statement, and chal- 

 lenges contradiction, that there is in that 

 locality a superior quality of raw products 

 of agate, onyx, jasper, chalcedony, etc., 

 more beautiful and in greater variety of 

 "olor, without flaws or imperfections, than 

 can be produced by any other lapidary lo- 

 cality or manufacturing site now estab- 

 lished in the old world or in America. 

 His article is a very interesting one, and 

 indicates a comprehensive knowledge of 

 the industry. 



The cathode ray is finding its adapta- 

 tion for a great variety of purposes. Re- 

 cently some very interesting experiments 

 were made in Oregon City, Oregon, by 

 Dr. J. C. Ferry, a well-known physician 

 there, and W. C. Cheney, superintendent 

 of the Portland General Electric Com- 

 pany. The rays were made to define the 

 free gold in gold-bearing rock as plainly 

 as if lying on the surface of the quartz. 

 This is probably the forerunner to a gen- 

 eral use of it in mining operations. If 

 they go on improving it as they have for 

 other purposes, it will not be long before 

 we shall hear of it being used to explore 

 the ground between tunnels and the sur- 

 face above. 



BOOKS AND MAGAZINES. 



GLADSTONE, HALE, FARRAR, GUNSAULUS, ETC. 



No matter what the subject might be 

 on which the men whose names are given 

 above might write it would be of absorb- 

 ing interest to the people. How much 

 more would this interest be if the subjects 

 on which they wrote were those to which 

 these men had given the greatest con- 

 sideration and the best thoughts of their 

 minds. In " The People's Bible History," 

 just issued by the Henry O. Shepard 

 Company, of Chicago, the matured opin- 

 ions of these men of the most learned 

 Biblical scholars in all portions of the 

 globe is concentrated. Of this book 

 Bishop John H. Vincent says: " What 

 Gladstone and Sayce have written ex- 

 pressly for its pages, giving the latest re- 

 sults of their largest knowledge, is enough 

 to justify even the most cultivated people 

 among us in the purchase of this admir- 

 able book, and the English ex-premier and 

 the eminent English archaeologist are only 

 two out of eighteen specialists who have 

 contributed to ' The People's Bible His- 

 tory." The beauty and wealth of illus- 

 tration and the exquisite presswork and 

 typography of the book are worthy set- 

 tings to the utterances of the great minds 

 set forth in its pages. The popular 

 edition of the book is to be had in cloth, 

 half russia and full russia. Agents are 

 wanted. An edition de luxe has also 

 been brought out, containing 1,283 pages 

 and 200 full-page illustrations and maps, 

 and is said to be a masterpiece of modern 

 bookmaking. 



"The Education of Women in Turkey" 

 is the interesting theme of an article by 

 Miss Mary Mills Patrick, President of the 

 American College for Girls, Constanti- 

 nople, whose educational work among the 

 women of Turkey, extending over a num- 

 ber of years, entitles her to write with 

 authority on this question. Professor 

 Thomas Davidson, who has just returned 

 from a two-years' sojourn in Europe and 

 the East, has written a highly interesting 

 article for this number entitled "The 

 Democratization of England," for the June 

 Forum. 



An entirely new near view of Grant will 

 be given in McClure's Magazine for June, 

 in a paper written by the man who was 

 chaplain of the Twenty-first Illinois when
