38 ANNUAL REPORT OF THE 



ture of salt from the Salt Lake brine, building stones including 

 some beautiful marbles and onyx in polished slabs, some cone-in- 

 cone specimens in the onyx; Minneapolis, Minn., Wisconsin 

 granites, slabs of various marbles and attractive panels of Kasota 

 stone; Cobalt, Ont., typical silver and cobalt ores, and specimens 

 of conglomerate and tillite from the Trethewey mine. 



The unique collection of stalagmites from the Shattuck Mine 

 at Bisbee, Arizona, deserves special mention. The Company 

 gave the stalagmites, and the Museum paid necessary expenses. 

 Three of the stalagmites average six feet high with base rock 

 enough to permit of a natural group. There is a claw-like stalag- 

 mite four feet high showing reddish coloration on the upper side 

 and snow white on the under side. A large number of smaller 

 stalagmites of remarkable shapes are colored yellow, cream, 

 purple, red, and pink. Some of them are of the most pure white. 

 Some have coral-like forms, and others are botryoidal or branching. 



Thanks are due to Mr. R. P. Wentworth for specimens of coal 

 and pre-Wisconsin till from Brighton, Mass., to Professor Raymond 

 for a specimen of dent-marks from Russia, and to Professor Palache 

 for specimens of folded gypsum and economic specimens. Pro- 

 fessor Woodworth very kindly gave his best striated pebbles from 

 the Permian tillite of Brazil. 



Mr. George C. Curtis's model of Kilauea is nearing completion. 

 On account of the difficulty of modeling the lavas, Mr. Curtis has 

 been much delayed in finishing his work. From pictures obtained 

 by kites, and taken by Mr. J. F. Haworth of Pittsburg, Mr. Curtis 

 has been able to model the lavas with great accuracy. 



Since the 17th of February, 1915, the Geological section of the 

 Museum has been open to the public on four additional afternoons 

 of each week, so that the collections can be seen on every day of 

 the year except July 4th and Christmas day. This has been made 

 possible by the generosity of the Visiting Committee in supplying 

 a watchman for Monday, Tuesday, Wednesday and Friday after- 

 noons. The watchman, Mr. Gurll, gives the attendance for the 

 five months as follows :— March 6679; April 6788; May 8346; 

 June 8309; July 10335; a total of 40457. The total for the new 

 days of opening is a little over one third of the whole. Owing 

 to the large attendance on Sundays, holidays, and a few other 

 days, an accurate account was not possible and the figures given 

 are below the actual number of visitors.
