the sturgeon. After digging down to the depth of about two feet, 

 the splinters of bone were more numerous than on the surface, and 

 in not a single instance have I found any bones that had been sub- 

 jected to the effects of fire, but the marrow had been removed by 

 splitting the bones with a stone or maul, as no indentations, such as 

 would be caused by an edged tool, were visible. 



None of the fragments of pottery indicated that any large vessels 

 had been used, but some of the designs corresponded precisely with 

 specimens obtained near the Rio Verde, Arizona. The latter are 

 usually glazed, an art which seems to have been unknown to the Rees 

 at that time. The texture of these specimens is rather fine, and 

 the color usually dark; the indentations have been made with a 

 small piece of wood, although in some of the ornamentation the fin- 

 gers were employed, as the five impressions show. The pottery does 

 not seem to have been baked, but sun-dried; this, however, is merely a 

 matter of conjecture, as the condition of the specimens after long 

 exposure has become considerably changed. Arrow-heads and 

 kindred flints were abundant. The smallest arrow points measured 

 but .4 of an inch in length, the typical form being triangular. The 

 finest point was one made of black silicious rock, three inches long, 

 and three quarters of an inch wide. It was knife-shape, i.e., rounded 

 at the one end like the blade of a common table knife, and elegantly 

 notched at the base. 



Bone implements were not rare; the finest piece of workmanship 

 being a fish-hook only an inch in length, and finely notched for 

 attachment to the line. These specimens were no doubt preserved 

 from decomposition by the dryness of the sandy soil covering many 

 of these refuse heaps, and the dry atmosphere common over the 

 country between the Missouri River and the Rocky Mountains. 



On certain land-locked Ponds as natural Meteorologi- 

 cal Registers. By L. S. Burbank. 



It is well known that among the small lakes or ponds so numerous 

 throughout New England, there are many which are entirely land- 

 locked, no water flowing from them at any season of the year. 



Some phenomena observed in a small pond of this kind in Lan- 

 caster, Mass., have suggested that valuable results might be attained 

 by more accurate and extended observations upon similar bodies of 

 water throughout the State.
