collection prepared during the year is nearly one thousand. 

 Besides these, a considerable number (about two hundred) 

 have been imported from Europe for comparison. Durincr the 

 vacation just elapsed, Mr. Wadsworth spent several weeks at 

 New York studying the collection and slides of the Fortieth 

 Parallfl Survey," made for and under the direction of F. Zirkel. 

 This department is now properly prepared for lithological in- 

 struction ; and, the services of Mr. Wadsworth having been 

 engaged exclusively for this work next j^ear, several students 

 have already apjilied for the enjoyment of the facilities thus 

 provided, and will devote a considerable portion of their time 

 to original lithological work. 



In the way of publications, the geological department of the 

 Museum has contributed to its Memoirs a work by Leo Les- 

 quereux, describing the fossil flora of the Tertiary auriferous 

 gravels of the Sierra Nevada, illustrated by ten double plates. 

 This work forms Fart 2 of Volume VI. of the Memoirs ; and 

 Part 1, which will complete the volume, is in press. The 

 beginning of a special geological library is now being placed 

 on the shelves in the rooms of the Sturgis-Hooper Professor ; 

 and, though incomplete, it is undoubtedly the best in this 

 country. 



With the co-operation of Professor Shaler, who instructs in 

 geology in the undergraduate department of the College, and 

 at tlie request of the Committee of the College Faculty having 

 the subject of post-graduate instruction in charge, a scheme 

 has been made out for a course of higher geological study at 

 the Museum. For this purpose, it was necessary to some extent 

 to combine the resources of the Museum and the College, and 

 some of the students offering themselves for this course will 

 undoubtedly be undergraduates ; who can, however, avail them- 

 selves of the post-graduate studies only by special permission of 

 the College Faculty, with the approval of the instructor sjje- 

 cially interested, and whose course is desired to be taken. The 

 scheme of post-graduate instruction, for the present, includes — 



I. Lithology. 

 II. Dynamical Geology. 



III. Palaeontology, Historical Geology. 



IV. Geological Field Work. 

 V. Economical Geology.
