A few words more on the first question of cost, which is one a practical mind is always asking and re-asking. The Aberdeen _Daily News_, which ought to know, for there are several wells in its neighborhood easy to study, states that a six-inch well can be put down for less than $2,300, and that any of the principal wells at Aberdeen, Hitchcock, Redfield, Woonsocket, Huron, or Yankton will irrigate six hundred and forty acres, which would bring the cost to less than $4.00 per acre for twelve inches of depth during the growing season. Mr. Hinds, of the Hinds ranch, has been charging adjacent farmers, however, only $1.00 per acre for water from his well, and considers it a paying investment. I cannot resist the temptation of closing this brief inquiry into and commentary upon this most important question by citing a picturesque passage from the Aberdeen _Daily News_:-- "The power of these wells is almost inconceivable. An iron bar eight feet long and two inches in diameter was accidentally dropped into the tubing of one of them, decreasing the flow for a short time, but it was soon ejected by the water with such force as to break the elbow of a strong iron pipe. When the well at Huron was first put down, no make of water mains was strong enough to withstand the full pressure of the water. The same may be said of nearly all the wells. The fact is that the artesian wells of this valley furnish _the mechanical power of the world_. This power requires no fuel, no engines, no repairs, no extra insurance. It never freezes up, nor blows up, nor dries up. _It can be managed by a girl baby_; $1,500 will furnish everlasting fifty horse-power. The wonder is that all the woolen, cotton, silk, and linen mills of the world do not rush to take possession of it. _It is a Niagara Falls already harnessed for use._ All the textile fabrics could be manufactured here _cheaper than in any other part of the universe_. The time will come when this will be recognized, and natural gas will be extinguished by _the giant gushing wells in Dakota_." This vivid writing, this rhetoric of artesian force, may be the result of an editorial fancy that has long bestridden a western boom, instead of tame old Pegasus; but, leaving out the manufacturing prospectus, there can be no gainsay of the statement that, with a million acres of the opulent Dakotan soil under the brilliant Dakotan sun, tended by two thousand artesian wells, the great drouth belt of the Northwest would be the richest agricultural area in the world.
