The specimens were carefully weighed. The specific gravity was deter- 

 mined by weighing in distilled water at a temperature of 65° Fah. 

 Numbers 7, 8, and 10 are very thin, about the thickness of a wafer. 

 No. 4 is about three one-hundredths of an inch in thickness. No. 1 is 

 about five one-hundredths of an inch thick on the edge and about eight 

 one-hundredths near the middle. The hole in the center has been bev- 

 eled on one face of the specimen with some sharp cutting tool, the marks 

 of which are discernible. It was evidently first cast, and has been rub- 

 bed down on the back, as presented in the drawing and photograph, 

 apparently by the use of sand, the striae being plainly discernible. The 

 face presented in the photograph does not appear to have been treated 

 in this way, but has the appearance of a casting. It is very much harder 

 than lead, and a fresh cut does not tarnish. It is apparently brittle, 

 having a crack nearly across its face. No. 8 is also cracked in much the 

 same manner, and has no markings. No. 7 is unmarked in any way. 

 No. 10 is pierced with a small hole near one apex, and there are numer- 

 ous punctures on the edges, which do not, however, pass through. No. 

 4 is marked on the face with lines which were evidently made with a 

 sharp pointed instrument, like a graver. The back shows the impress 

 of a mold. It is perhaps the most interesting of the collection. 



No. 5 is evidently a bullet, much harder than lead, which has been 

 perforated with some sharp pointed tool, making a hole of large di- 

 ameter at the two ends and smaDer in the center, such as would natur- 

 ally be made by a small penknife. The hole in this and also the two 

 holes in the end of No. 9, are filled with a substance resembling rosin, 

 which gives to the lizard-shaped specimen, No. 9, the effect of two bril- 

 liant eyes. This No. 9 has been broken in two places. Ithasbeen sug- 

 gested that this singular shaped specimen served as a spoon or other 

 instrument for eating, an idea suggested by its trough-shaped underside, 

 which resembles a cheese-knife, such as is nsed by grocers. The ma- 

 terial is hard and brittle, and there is a trace of gold in the tail end. Its 

 thickness is eight one-hundredths of an inch in the center, one edge be- 

 ing considerably thicker than the other. This piece resembles the head 

 of a cat-fish. No. 2 is eighteen one-hundredths of an inch thick in the 

 center, and the edges have been rubbed down to about from six one-hun- 

 dredths to eight-one-hundredths of an inch in thickness. The point is 

 sharp. This is evidently cast, the indentations of a rather smooth 

 mold, such as appears on the surface of smooth castings, being very 

 plain, especially on one side. This appears also to have been rubbed 

 down as with sand and water, and the edges beveled. 



No. 3 is about three one-hundredths of an inch thick, somewhat thinner 

 on the edge of the axe, and thicker at the top. It is evidently hammered, 

 and is very smooth. Examining the specimens on the basis of their rel- 

 ative specific gravities, the low values found for the gold specimens is 

 most noticeable. This shows them to be largely alloyed with much 

 lighter metals, such as copper or brass, silver, &c. The alloys of the
