42 REPORT OF THE SECRETARY. 



which were recognized at once as indications of another quarry, and Mr. 

 Cashing was directed to make a thorough examination of it. Here, as 

 in Virginia, depressions along the hill-side in which the qn any occurred 

 showed that the Indians had worked the underlying ledge, although ex- 

 cavations subsequently made revealed the fact that they had depended 

 mainly upon surface material for then- supply. Large numbers of un- 

 finished vessels, quartz -picks, hammer-stones, &c, were here found. 



Another quarry has been repored by its proprietor, Mr. M. E. Holmes, 

 as occurring on the right bank of the Potomac above little Falls. This, 

 though rich iu ancient remains, has not yet been thoroughly examined 

 by the Institution. 



Mr. J. D. McGuire, of Ellicott City, Maryland, called our attention to 

 s till another quarry, not unlike the one on Rock Creek, and remarkable 

 for the fine specimens of Indian work that it furnished. Through the 

 hospitality and kind assistance of this gentleman, Mr. Cushing was en- 

 abled during the month of December to make a personal examination 

 of the place, and secure for the museum nearly two hundred superior 

 specimens. 



It may be well to add that since the discovery of the Virginia quarry, 

 public attention having been drawn to this kind of research by widely 

 circulated newspaper notices, similar sources of aboriginal supply have 

 been discovered in Rhode Island, Massachusetts, Connecticut, Pennsyl- 

 vania, Tennessee, Georgia, Alabama, and Wyoming, from several of 

 which the Institution has already received specimens. 



An aboriginal quarry, recently discovered near Providence, R. I., on the 

 farm of Mr. Angell, was visited by myself in July, accompanied by Pro- 

 fessor Jenks, through whose assistance I was enabled to obtain specimens 

 of the unfinished pots and of the mining apparatus. 



Reference has already been made to the plans of an extensive work 

 on the American Stone Age, to be prepared under the direction of the 

 Institution, to serve as a manual for this department of archaeology. The 

 publication of the circular referred to as among the publications of the 

 Institution for 1878 has been of great benefit in bringing in both large 

 and small collections, as will be seen by reference to the list of donations. 

 Every part of the country is represented in these returns, which are so 

 many indeed as to render it somewhat invidious to select any for special 

 notice. Justice, however, to the contributors, makes it proper that I 

 should mention a few of these in greater detail. 



The first collection to be noted is that presented by Mr. A. B. Critten- 

 den, of Middletown, Conn., a large and extensive one, made during sev- 

 eral years of effort. This is particularly rich in the shell heap or Kjok- 

 eninoedding deposits, from Cape Cod, showing a varietvand complexity 

 not previously exhibited. 



To one correspondent, Mr. J. E. Gere, of Riceville, Wisconsin, of the 

 Institution, is indebted for an important increase of its collection of 

 ancient copper implements. Mr. Gere, during a visit to the Institution,
