While the miners have not yet determined its full dimensions, it weighs 1500 pounds, and its value is estimated, even to a cent If there is any method by which the value of a nugget of unknown dimensions can be so accurately computed, mining men would be interested in knowing more about it.

Prof. Fortier of the Utah Agricultural college has investigated the cause of the break in the Three Mile reservoir dam, which resulted in such great damage to property. In his report he says: The immediate cause of this failure think was percolation through the top part of the dry porous embankment at the northeast end, where the made embankment joined the original surface. The water, in our opinion, never flowed over the top of the dam. The water-wa- y is more than two feet below the top and there is no indication that any water ever flowed through the waste way. The upper half of the embankment is very dry and porous and with the wash of the waves on the inner side the water must have found its way through the bank some two or three feet below the top or at the water line. It may have taken hours for this small stream to have percolated through the dam, but having once got well started, nothing could stop it. In the building of earthen dams irrigators and many good engineers seem to overlook the fact that dry earth as it exists in nature is porous, containing from 30 to 60 per cent open space which is either filled with air or water and usually with both. To scrape such earth into a bank may do quite well for a railroad, but it is never safe to hold we water. To illustrate the above, last spring i took a yard of gravel, fourth yard of fine sand and d of clay, making one and ya,rds and by wetting and ti 1 r,educed the volume to less ne and one-ha- lf yards. one-yar- MINING REVIEW. N It is easier to tear down than to build up. It requires less labor and less pluck to criticise from afar than to lend a helping hand for the betterment of things. Any idling numbskull can rail and find fault, but it is not by raillery and fault-findin- g are accomplished. that reforms The foregoing observations are suggested by the attitude of a great many well-meani- and highly ng respectable citizens toward the Salt T.ake Stock and Mining Exchange. These worthy gentlemen make haste to belittle, ridicule and condemn the work of the exchange and the manner in which it is done, and while admitting the bene- ficial influence of a properly conducted exchange, refuse to be satisfied with the manner in which the Salt Lake institution is conducted. To this class of people The Mining Review would suggest that none of them are barred from membership or active participation in the proceedings, and if they are not pleased with the way the exchange is run, they might take a hand and run it themselves. When the heavy moneyed men of the city, the mining operators and others who are more directly interested than any other class in the protection of the mining stock market wrap themselves up in their dignity and decline to have anything to do with the exchange, they have no right to find fault because that exchange establishes low quotations upon stocks in which they are interested. If they do not care to protect themselves and their holdings, certainly the protection will not be volunteered by the stock brokers. Every break in a high priced stock is likely to seriously affect some holder who has his shares deposited as collateral for a loan, but if those who are interested would give support to their stocks there would be fewer breaks. Brokers may be depended upon to manipulate prices up and down and scalp the market; that is their business, and the investor or speculator who refuses to come to the rescue when his interests are attacked may expect to be frequently upset. 7 havthe said gearing, said driving-ba- r a splineway-join- t therein and one ing section thereof carrying a clutch rigid thereon, but adapted to move lonitudi-nall- y to engage with the power-shaf- t.
