EEPORT OF THE SECRETARY. 37 



'fUp to this time his life, although quite prolific in results, had been 

 mainly one of study and preparation, and very few, indeed, of his age 

 could be found so well prepared to undertake extensive and far-reaching 

 investigations. Upon coming to Washington the investigation of the 

 quarry industries of the country, which was undertaken under the joint 

 auspices of the Smithsonian Institution and the census, opened up a 

 broad and almost unoccupied field for his activities, and he undertook it 

 with all the earnestness and zest of one well prepared and confident of 

 accomplishing much good in the increase of knowledge. The plan of this 

 work as laid out by Dr. Hawes was very broad and comprehensive in its 

 scope. Besides the collection, arrangement, and study of the statistics 

 of the industries, it included the study and description of the occurrence 

 and preparation of building stones; the collection of specimens from all 

 the regions of production which, when properly dressed, should form a 

 graphic representation of the natural materials of construction of the 

 whole country; the thorough examination of these specimens microscop- 

 ically, chemically and physically ; and, in fact, the thorough and com- 

 plete study of the subject in all its branches ; so that had he lived to 

 complete the work there can be no doubt that it would have been very 

 fruitful of good results. His earnestness and zeal, however, led him to 

 overtax himself, and it was not long before it became evident to his 

 friends, although not to himself, that his health was being seriously 

 undermined ; but near the end of the year even he became alarmed at 

 the evident signs of consumption that had developed themselves, and 

 he decided to take a respite from active work, which he did by a trip to 

 Bermuda. This, however, failed to afford any relief, and he gradually 

 sank after his return, until finally, as a last resort, he went to Colorado. 

 But the disease was too far advanced to be checked, and he lived but a 

 short time after his arrival in Colorado. The final dissolution came 

 rather suddenly, as up to the day before his death he was able to be up 

 and dressed and about the house. His remains were interred at Wor- 

 cester, Mass., June 28. 



" The removal of one so well prepared and adapted to undertake exten- 

 sive investigations is a great loss to the world of science. Had he lived 

 there can be no doubt that he would have reached many valuable re- 

 sults, and his untimely death was sadly deplored by all who knew him. 

 Dr. Hawes's contributions to science were mainly in the line of his spec- 

 ialty — microscopic lithology — and consist of some twenty articles pub- 

 lished in the American Journal of Science ; three in the Proceedings of 

 the National Museum ; an annual report upon geology and mineralogy 

 in the Annual Report of the Smithsonian Institution for ] 880, and part lY 

 of Volume III of the Report of the Geological Survey of New Hamp- 

 shire, entitled the ' Mineralogy and Lithology of New Hampshire '. The 

 latter covers 251 pages quarto, embellished by twelve plates, and is his 

 mostvaluable and important completed work. It includes the results of 

 the examination of between two and three hundred thin sections of rocks,
