afterwards collected for me in the Upper Carboniferous of eastern Kansas. 

 Dr. Edwin Kirk, now a member of the staff of the United States Geological 

 Survey, made for me an extremely valuable collection in the Trenton beds at 

 Kirkfield, Ontario; three others in the Onondaga, Hamilton, and Portage rocks 

 of New York; and still another during a season's work in the Hamilton of 

 northern Michigan. 



The veteran collector, Frederick Braun, now of Brooklyn, New York, 1 

 whose specimens from Crawfordsville and Cincinnati in former years found 

 their way to all the museums of Europe, carried on field work for me from 

 1906 to 19 14, collecting echinoderms exclusively. He has a keen eye for fossils, 

 and is a master in recovering them from the rocks when a productive bed is 

 located; in this kind of work his patience, perseverance and resourcefulness are 

 without limit. During the years mentioned he carried on large quarrying 

 operations at Crawfordsville, Indiana, sending in 115 boxes of fossil crinoids 

 as the result of a season's work, in which he exhausted the locality for any 

 systematic collecting; another season he worked in a similar way a rich bed 

 found by him on Indian Creek, from which he filled 25 boxes ; he quarried dur- 

 ing three seasons in the Rochester shales at Lockport, New York, with most 

 important results in the way of finely preserved specimens such as had not been 

 obtained before at that celebrated locality; another season's work was done at 

 Cape Girardeau, Missouri, resulting in the securing of the extraordinary 

 material described in my memoir on the genus Scyphocrinus. In addition to 

 these long campaigns he made several more general trips, on which he collected 

 in the Onondaga and Hamilton of New York, the Niagaran of St. Paul, In- 

 diana, and of Decatur County, Tennessee; the Ordovician of Knox and Granger 

 counties, Tennessee, and of Mercer and Woodford counties, Kentucky; the 

 Linden of Perry and Benton counties, and the Niagaran near Nashville, Ten- 

 nessee; the Knobstone of White's Creek, Tennessee, and of the Knobs of 

 Kentucky and southern Indiana; the Kaskaskia of Monroe and Randolph coun- 

 ties, Illinois; and the Ordovician of the Oswego region in Illinois, and of 

 southern Wisconsin. 



In 1905 I purchased the large collection made by Professor W. F. Pate, of 

 Lebanon, Kentucky, chiefly in that state and Tennessee. He was then on the 

 staff of the Kentucky Geological Survey as Associate Geologist during the 

 summers, but through the courtesy of the Director, Dr. Charles J. Norwood, 

 I was enabled to secure his services for a collecting campaign in the Niagaran 

 of Decatur County, Tennessee, which had been a favorite collecting ground 

 for paleontologists since the times of Troost and Roemer. This he prosecuted 

 during the two following seasons, tracing the fossils to their strata in place, 

 and quarrying, which resulted in securing more finely preserved specimens
