and in the pages of our Bulletin, he will instruct us concern- 

 ing these things which are of so vital an importance. 



He. has most generously acceded to our wishes and, although 

 it will be a great tax upon his time and a huge draft upon his 

 professional duties in the University, he will, from time to 

 time, furnish us with monographs which will be presented to 

 the world in our Bulletin. 



These articles probably will run a period of two or three 

 years, and embrace not only in detail the food fishes, but gen- 

 erally the rare fauna and flora of our waters, and the hydro- 

 graphy of many miles of our coast. They will be illustrated 

 with half-tone and colored tableaux of under-sea life, of a 

 character heretofore not imparted in any publication relating 

 to the Pacific Coast. 



We hope to present the first paper of this series in our Bulle- 

 tin for next July. 



Work on the 100-inch telescope is proving to be all and 

 even more than was expected. Mechanically the working 

 parts are doing everything expected of them. It is an enor- 

 mous test of mechanical skill for the most ponderous tele- 

 scope in the world to have all its multifarious parts so nicely 

 adjusted that they move upon each other with absolute pre- 

 cision. 



Optically the great mirror has already proved to be won- 

 derfully accurate. A few test observations have been made, 

 and so far they have shown the great mirror to be a perfect 

 disc, capable of revealing exceedingly minute detail. The 

 workmen are engaged in grinding and polishing some small 

 plane and concave mirrors to be used in focusing and convey- 

 ing the gathered light of the large mirror to the eye of the 

 observer. This powerful instrument will probably be in full 

 observational use in the early spring months.
