6 GEOLOGY OF OLD HAMPSHIEE COUNTY, MASS. 



perfect Triassic tracks found up and down the valley, with which discovery 

 the names of Dexter Marsli,^ Dr. James Deane,^ and Dr. Roswell FiekP 

 were also connected. Previous to the year 1884 I was for a long time 

 accustomed to arrange the successive senior classes of Amherst College on 

 the lawn before the house of Dr. Field, in Gill, and the old man would 

 come out and give the boys a lecture on the "true theory of bird tracks," 

 claiming, and I think with justice, that he first disco'S'ered the quadrupedal 

 character of the animals which made the tracks. 



1841. Final Report upon the Geology of the State. This summarized 

 the geology of the region to date, adding, however, very little to the report 

 of 1835, while the discussion of the "bird tracks" went on vigorously until, 

 in 1844, the Report on Ichnology brought together all that was known 

 on the subject, with abundant illustrations — indeed, vastly increased what 

 was before known, though it did not close the subject, since articles 

 descriptive and controversial continued to flow from the pens of all those 

 mentioned above, as well as more elaborate works from the two sons 

 of President Hitchcock, while the last scientific article published by the 

 President himself (1863) was concerning New Facts and Conclusions 

 Respecting the Fossil Footmarks in the Connecticut River Valley. 



1860. Illustrations of Surface Geology. With this, one of the pioneer 

 works in a field which has since become most popular, the great work of 

 Pi'esident Hitchcock on the geology of the Connecticut closed. 



1863. Reminiscences of Amherst College. This book contains an 

 aftennath of opinion on the geology near Amherst. 



I may here mention, in conclusion, several jjersons who have advanced 

 the science of mineralogy in the region, or at least have gathered valuable 

 collections for the use of other. Mr. James T. Ames, proprietor of the 

 well-known foundries at Chicopee, was led, perhaps from his connection 

 with the Chester emery bed, to gather a collection very valuable for the 

 illustration of the local mineralogy ; and Dr. H. T. Lucas,* who had a large 

 share in the discovery of the emery at Chester, has been identified with 

 the exploitation of this and many other mining properties in Hampshire 

 County for many years. Mr. M. A. Brown, formerly of Northfield, has 

 done very useful work in exploring the mineralogy of eastern Franklin
