ttracted the attention of a young Yale graduate, who is editing an evening paper in Sioux Falls, and he began to collect the views of experts on the question of artesian irrigation. Mr. Tomlinson, of the _Argus Leader_, had, probably, no idea of the mass of literature with which the theme was potential, and the way the papers, even outside the State, have followed his lead must be flattering to him both as an editor and public-spirited citizen. My indebtedness to Mr. Tomlinson for some of my facts being thus cheerfully acknowledged, let me plunge _in medias res_ into the turbid waters of the irrigation problem. Shall we make it "rain from the earth, when the sky fails"? is now, thanks to an editor, the great Dakotan question. It is a question of many facets. What does it cost, will it pay, is it safe, or must it ultimately poison the ground by sowing the land with salt like a vandal conqueror, and creating a Sahara for immediate posterity? Finally, if it is to be done on a proper scale, how shall the burden of the introduction be borne; by the township, the county, the State, the nation, or by private enterprise? Let us take up these points _seriatum_. Professor Upham, of the United States Geologic Survey, a man of unquestionable honesty and no mean authority generally, thinks that the cost alone demonstrates the futility of attempting the artesian system. He bases his opinion on the Jamestown well, which cost $7,000. Yet if, as there seems to be no doubt, irrigation will increase the wheat crop by at least ten bushels an acre, even this large expense would be warranted by the increase in land value. But it is probably not known to Professor Upham that wells between Jamestown and Huron are being sunk now for half, in some cases one-third, and in a few cases one-tenth of his reckoning. So with this change of former figures, the question of cost may be said to cut no figure. But will it pay permanently, and to what extent? Prof. G. E. Culver answers this question with great ability. He says positively that it will not materially change climate nor by attraction increase appreciably the annual rainfall, though he thinks it may tend to equalize the distribution of the rainfall. As to climate one might be inclined to disagree with him. There has certainly been a great change in the climate of Utah since irrigation was begun there, and an appreciable change in some parts of Southern California, though not in Colorado, as
