There is every reason to expect that the earnings for the year 1892 will increase in the same proportion as in the past, and will continue for a great many years. The Silverton Railroad is also authorized to build up the Animas River. We would like very much this year to extend the road in that direction some 12 or 15 miles in order to reach a very rich and valuable mining district. There are a great many very extensive mines of low grade material lying between Silverton and the summit of the range towards the northeast, and our object in offering to you the bonds of the present line of the railroad is to obtain funds to extend the line up the Animas River. We can offer you at the present time $400,000 out of a total of $425,000. These bonds are issued in denominations of $1,000 each. The interest is payable semi-annually on the first of April and the first of October at the rate of six per cent per annum in U. S. gold coin. Yours very truly, John L. McNeil,[3] Treasurer.

Vol. XXIII.—September, 1890. THE TURN-TABLE ON THE MAIN TRACK OF THE SILVERTON RAILROAD IN COLORADO. By C. W. Gibbs, M. Am. Soc. C. E. WITH DISCUSSION. The Silverton Railroad is a short line but 17.5 miles long, and has the reputation of being the steepest (5 per cent. grade), the crookedest (30 degree curves) and the best paying road in Colorado; and is owned by one man, Otto Mears. It also has a turn-table on its main track, and it is the purpose of this paper to describe it and explain why it was so placed.
