(gbitorioi (Comment. Now that there i a marked movement of cap ital toward our mine, a word of advice tolhe owner of " prosjwla " will not be out of place. The time ha gone by when claim can be sold ujion the strcnglh of away from surface crop ping. A mine can I sold, but mere proHtect are not In demand, Sensible business men and they arc the one who arc now making thew investment, want to ace what they are baying. They w ill pay fifty or a hundred thou sand dollar for a mine no developed a to actu ally show the qtuntity and quality of the ore it contain, when they would not invent a thou oand in a prospect, no matter how rich the sur face rock may be. Capital i going into our mining district in abundance, but the careful observer will see that it in being invented in mine, and not In prospect hole. In every quartx district In the Went, are to be found aeon of men who have made location, and are only doing enough work on their claim to ful fill legal requirement. Their assay show fig ure far greater than those of neighboring mine, which are Wing worked on a large scale and are paying dividend; and they are waiting fur the " coming man " to buy them out. All they have to exhibit I a location, a act of assaycr'a certificate, and the fad that their neighbor are doing well ujxm oorcr prospect. IWti cal men are too wise to place their money upon such an uncertainty, when there arc other good claim for sale, In which the ore ha been ex )mv1 to luch an extent a to demonstrate its value and nnanence. Occasionally, to le sure, a prosjvt of this kind I sold, yet it bring but a trifle, rutnparcd with price paid for de velop! mine, and the locator receive $1 ,000.00 for hi claim, when a little development work would have made it worth ten or twenty time aa much. There are, of course, many who are not able todothl development work, but that it their misfortune, for which Intending pur chaser are not responsible. They have no more just cause for complaint than ha the own er of a peanut stand because hi sale are not a large a the grocery store on the corner. What they ought to do, I to stop complaining, and devote to their claim some of the time and money expend! at the saloon. In this way, they may be able, gradually, to place their projterty in a condition for sale. One thing is certain, and the sooner it is realized the better it will be for claim owners, that there is a large amount of capital looking for mines, and but little in search of propped holes. If the prosperity of a section can be judged by the amount of railroad building in progress and excrience proves that they are closely allied-then must the Northwest be entering u jwn a neason of great prosperity. A brief enu meration of the various railroad enterprises up on which actual work of construction is pro gressing, will suffice to show the condition of affair. The greatest activity is exhibited in Montana, where the Northern Pacific and the Manitoba systems are building rival lines. The latter, in its westward march, has just reached the Montana line, and is pushing construction night and day, at a rate previously unequaled in railroad building. It will reach Fort Benton by September, and Great Falls by December. By that time, work on the Montana Central will be completed from Helena to Great Falls, giving the Manitoba an entrance to the chief city of the territory. Work is also progressing on the line of the same road from Helena to Butte. Two branches of the Northern Pacific, one from Prummond to Phillipsburg, and one up the Bitter Root valley from Missoula, are under construction. The gauge of the Utah & Northern i being changed from narrow to stand ard width. Engineering parties are in the field for half a dozen other lines, but actual construc tion ha not yet begun. In Idaho, the branch line from Nampa to Boise City is now in pro gress. In Washington, the southern extension of the Spokane A Palouse, the final work in the Cascade on the line of the Northern Pacific, the work on eighty miles of the Seattle, Lake Shore Eastern, thirty miles of the Seattle & West Coast, and on the Puget Sound & Gray's Harbor road are progressing rapidly. Railroad construction in Oregon is represented by the line being built from Pendleton to Wallula, by the eastward extension of the Oregon Pacific from Albany, by the completion of the narrow gauge line from Elk Rock to Portland, and by
