most favored portions of the globe and far superior 

 to the average fruit found in the market. But mag- 

 nificent orchards have been left defenceless against 

 the commonest pests until it is hardly possible to find 

 a specimen of really perfect fruit. The thing has 

 gone so far that nothing but stringent laws rigidly 

 enforced will now avail to abate the evil; if this is 

 done, and there is then a systematic effort to improve 

 the methods of putting the fruit upon the market, the 

 Utah fruit industry will expand to large proportions 

 and yield large and steady profits. 



By an unaccountable error the map 

 Runoff showing the runoff of the United States, 

 Map. published in the last number of THE AGE 

 in connection with Major Powell's article, was credited 

 to the Weather Bureau. It is in reality the result of 

 thousands of observations and computations made by 

 the Hydrographic Division of the Geological Survey. 

 To Mr. F. H. Newell, more than any other individual, 

 credit is due for this laborious and enlightening 

 work, which will benefit those engaged in the irriga- 

 tion industry for many years to come. Mr. Newell 

 belongs to that class of scholarly scientific young 

 men who have been attracted into the government 

 service by the opportunities it offers to perform 

 notable work in exploring new problems and new 

 fields. He has an enviable amount of achievement 

 behind him and apparently a very important career 

 ahead of him. He is mapping the ground whereon 

 the great developments of the next century will work 

 out undreamed-of results.

 It is evident to any one who carries out the calcula-

 acre is two tons the acre of grass will transpire one

 as stated.

DEPARTMENT OF THE INTERIOR, 

 UNITED STATES GEOLOGICAL SURVEY, 



WASHINGTON, D. C., Feb. 15, 1894. 

 MR. WILLIAM E. SMYTHE, EDITOR OF THE IRRIGA- 

 TION AGE, 1167 the Rookery, Chicago, 111. 

 Dear Sir: In reading my article on "The Water 

 Supplies in the Arid Region," in the February num- 

 ber of THE IRRIGATION AGE, I have discovered an 

 error in the upper paragraph of the right-hand column 

 of the 54th page. From the wealth of illustrations at 

 hand I selected one which involved an error, and I 

 was so limited for time in the preparation of the arti- 

 cle that proper examination of the manuscript was not 

 possible. Had I seen printer's proofs the error would 



doubtless have been detected. I am preparing an- 

 other article in which the subject of the absolute duty 

 of water will beset forth in a manner that will exhibit 

 the facts more thoroughly, and I propose to offer it for 

 publication in THE IRRIGATION AGE after the ap- 

 pearance of the article on " The Ownership of the 

 Lands of the Arid Region." Please publish this state- 

 ment. Yours cordially, 



J. W. POWELL.

 Chicago*!!!. L/L< ^ ) " sc ' ent ' st an d educator, was born 

 Nov. ig, 1892. at Hampden-Sidney, Va., in 1855. He 

 is the son of Robert Lewis Dabney, D. D., LL. D., 

 theologian, many years a professor at the Union 

 Theological Seminary of the Presbyterian Church, 

 now professor of philosophy in the University of 

 Texas, and was " Stonewall " Jackson's chief-of-staff 

 and biographer. President Dabney graduated at 

 Hampden-Sidney College with the degree of A. B. in 

 1873, taught a classical school one year and graduated 

 at the University of Virginia in 1877. He was pro- 

 fessor of chemistry and mineralogy at Emory and 

 Henry College, Virginia, 1877 to 1878, studied chem- 

 istry, physics and mineralogy at Berlin and Goet- 

 tingen, Germany, from 1878 to 1880 inclusive, receiv- 

 ing the degree of Ph. D. at the latter university. 



He was elected professor of chemistry in the Uni- 

 versity of North Carolina just before returning to 

 America, and soon thereafter was elected State 

 Chemist of North Carolina. In 1881 he became Di- 

 rector of the North Carolina Agricultural Experiment 

 Station at Raleigh, and also State Chemist of the 

 Geological Survey and Board of Health. While 

 there he published a number of papers in the scien- 

 tific journals on points in organic and agricultural 

 chemistry, a large number of bulletins and five 

 annual reports of the Experiment Station. He con- 

 ducted explorations for phosphate in eastern North 

 Carolina, and was the first to discover and bring 

 these deposits to the attention of the scientific and 

 commercial world. He made similar explorations of 

 the pyrites deposits and made collections of the use- 

 ful minerals of the same State for various expositions 

 and the State museum. He discovered cassiterite 

 (black tin) and a number of other new and valuable 

 minerals in this section. Publications on these sub- 

 jects were made in State reports and the journals of 

 various scientific societies. Dr. Dabney was the rep- 

 resentative of the State of North Carolina at various 

 expositions and elected the chief of the department 

 of Government and State exhibits of the New Or- 

 leans World's Exposition of 1884-'85. As chemist to 

 the State Board of Health of North Carolina he pub- 

 lished various papers on drinking waters, foods, 

 drugs, etc. While in North Carolina, Dr. Dabney 

 was instrumental in providing buildings, with labora-
