760 Cathinite. [July, 
mon form in the oldest mounds, is made of a very dark red pipe- 
stone, polished, from an extensive mound in Rockingham town- 
ship, six miles south-west of Davenport. Three other specimens 
from mounds in Louisa county, Iowa, belong to Mr. C. T. Lind- 
ley, but are at present deposited in the same museum. One isa 
bird-shaped pipe of a bright dark red color; another is also of 
the bird form, but is of a solid gray color; the third is also gray 
and plain. 
Dr. C. A. White, in a recent letter to Mr. Pratt, writes: “ You 
are quite right in supposing that some portions of the pipestone 
from the Great Red Pipestone quarry are of an ash or similar 
color, while other portions are spotted or mottled, or both. The 
prevailing color is red, the color so commonly seen in pipes, and 
the light colors are rather rare. It is not improbable that the 
layer which furnished the best material for pipes may have been 
found at certain local spots to have had a lighter shade than the 
prevailing color, so that there might at certain times have been 
more of that color found than the whole deposit will average. In 
short, so far as color is concerned, I do not know why all the 
specimens you refer to may not have come from the Great Red 
Pipestone quarry.” 
After a thorough study and comparison of the various spe 
mens of this collection, both modern and ancient, Mr. Pratt as 
sures me that beyond doubt the material of all the pipes alluded 
to or described above is true catlinite. 
A human headed pipe four and a half inches in length and 
three in height, in the collection of Hon. Horace Beach, of Pran l 
du Chien, Wisconsin, was found in a mound at Des Moines, le 
The form, however, does not indicate a very high antiquity ; the 
specimen belonged doubtless, to an intrusive burial. Half "i 
platform and the head, which is situated near one end, is of a aut 
reddish color, whilst the other half of the base is a dark om 
brown witha greenish tinge. The line, showing where the a : 
colors unite, is very distinct. After a careful examination yer’ | 
specimen I unhesitatingly pronounce the material catlinite. s 
other pipe bowl from the same collection is fashioned ee - 
bright olive colored variety of catlinite, in which numerous > k: 
spots of a lighter color are visible. This pipe was taken m 
mound in Prairie du Chien, Wis. Mr. Beach is of the oPh 
that it was a Winnebago production, belonging to 4 seco o
