cality, in company with his son and Dr. Abbott, had been exceedingly 

 interesting, including the examination of the- exact points of occurrence 

 of the worked flints at different depths of the gravel-bank, as well as 

 of modern Indian implements at many points over the surface, but 

 never imbedded in the gravel. He expressed his own very clear and 

 decided impressions as to the care and fulness of Dr. Abbott's re- 

 searches, and the substantial accuracy of his results. 



In reply to an inquiry of Mrs. E. A. SMITH, Dr. Martin further 

 stated that the objections of Prof. Boyd Dawkins related to the origi- 

 nal and incorrect views of Dr. ABBOTT, who. had been misled by Prof. 

 G. H. Cook's estimate of the geological age of this gravel deposit. Dr. 

 Abbott also believed he had made an important discovery in a speci- 

 men of human tooth, which he had struck with his cane out of a gravel 

 bank, and whose rolled, water-worn condition indicated a vastly greater 

 age. 



The President stated that Prof. Dawkins had never visited the 

 locality, and had not expressed to himself any positive opinion. It 

 was an interesting fact that, in Dawkins' classification of the early 

 races of men, he calls the first race the River Gravel Men, afterward 

 followed by the Cave-dwellers.

Mr. G. F. KuNZ exhibited a supposed emerald from Gibsonville, 

 Guilford County, N. C. Mr. Smith, a farmer, while ploughing on his 

 farm in March last, turned up an irregular shaped, smooth-faced stone, 

 the size of a hen's egg. It glittered in the sunlight. Mr. Smith took 

 the stone to Greensboro, where a jeweller pronounced it a genuine 

 emerald weighing nine ounces. The jeweller was also of the opinion 

 that smaller brilliants clinging to the central stone were diamonds. 



The fact was published and aroused the greatest interest among 

 jewellers and mineralogists. A diamond miner visited Mr. Smith and 

 offered him $1,000 for the gem. Mr. Smith refused the offer, being 

 assured that the emerald was the second largest in the world and of 

 immense value. He brought it on to New York and intrusted it to a 

 banker, by whom it was ultimately submitted to Mr. KuNZ for exami- 

 nation. After subjecting the stone to various tests, he found it to be a 

 crystal of quartz, penetrated by long, hair-like crystals of green acti-
