THE MINES
What Has Been Done at The
 JumbO.-MinOr Notes

 made brief mention of the Jumbo mine at Sulzer, on the west coast oi Prince of Wales Island, owned and operated by the Alaska Industrial Company, as being about to enter the list of the steady and profitable pro- ducing mines of the Ketchikan dist. rict.
 The record of this mine, could it be accurately related in detail, would form an interesting chapter of the his tory of the district, and of the trials and tribulations attendant upon a prosecution of the work of develop ment. It would be record of rare faith and steady perseverance-on the part of one man at least-leading to a final success as we'll deserved as it has been hardly earned. It was in the summer of 1899 that Hon. William Sulzer, then as now representative in Congress from the 10th district oi New York, came to Alaska, and be- coming imhued with belief in the great undeveloped mineral wealth of this region, took over from the orig inal locators, among whom was Mir. J. L. Gould, then missionary at Howkan, now resident of Sulzer, the locations for the development of which he proceeded to organize the Alaska Development Company, with Hon. J. P. Jones, then U. s. Senator, as its first president. From that time on until the advent of the present alto gether conservative, careful and com petent local management, the attempts at development were but succession, one after another, of disappointments to those who were induced to put their money into the enterprise. First, a "has been" expert, accompanied by doctor, and since ascertained to have been off his base mentally, was sent up at heavy expense to do some work and report on the property, the last of which he never did, but on the con- trary disappeared after leaving Alas ka and was never afterwards heard from.
 Then came an ex.Universalist preacher, who knew no more about mining than he was supposed to know about the place of everlasting tor ment,, in which he professed not to believe, who established camp, did some desultory work in the way of development, expended all the money furnished him, incurred goodly amount of indebtedness, and then wended his way back to the place whence, so far as the welfare of the company was involved, it had been better had he never departed.
 Then came, as his successor, a harum scarum youth, belief in whose knowledge of mine management was based solely on the fact that he was the son of somewhat noted English mining engineer, and who, appropri- ating to his own use the funds sent him with which to pay off the indebt- edness incurred by his predecessor, like the latter folded his tent and silently stole away and was heard of no more in mining circles. Indeed, until the advent of the present local management, it is safe to assert that the larger half of the large amount of money furnished for development, was either foolishly expended or misap- piled to other than development pur- poses. All this cost the company a great deal of money without the ac- complishment of substantial results. That far different condition of affairs has been attained under the present management is fully evidenced by the fact that nothing but transport ation is now lacking to give the Jumbo a leading place among the profitable producers of the district. It now has in it's bins at the mine and wharf 300 tons of ore, which is ex- pected to yield better than per cent. copper, with some gold and silver, and which, not taking the gold and silver values into the account, ought to yield the company net returns, over and above all costs of mining, trans. portation, smelting and refining, of more than $50, ,OOO. The first ship. ment of from 1000 to 15OO tons is ex- pected to be made the coming week.
 The Jumbo mine lies in two distinct ore formations, one known as the magnetic and the other as the basin group. The magnetic shows enor. nous outcrops of magnetic ore carry ing low percentage of copper, gold and silver, in which large amount of development work has been done by tunneling, exposing hundreds of thou sands of tons of ore. The equipment however, is not at the present time sufficient to enable the management to mine and handle this ore economic ally, and for the past year develop ment and mine work has been almos exclusively confined to the basil group, the ore of which is high grade chalcopyrite.
 The Basin part of the Jumbo ha been developed thus far by four tun nels and large surface workings. Th' main working tunnel is the lowest o the four, and into it all the ore mine, above its level is delivered by gravity From this tunnel the ore is trammet
