THE WAR-POINT. 
By JosEPH WIGGLESWORTH. 
I find that many young collectors are puzzled 
over the war point. When they obtain one 
they do not know what it is, and exchange or 
pass il off as they do the more common arrow- 
head. The war-point is a three-cornered arrow- 
head without a shank. The shaft of the arrow 
was split, the war-point inserted, and then 
wrapped with the sinews of the deer, The first 
impulse of the person shot was to draw out the 
shaft, which always left the point to work its 
way in. As poisoned points were used, it can 
be supposed that the wounds always proved 
fatal. The war-points are of benefit to the 
Archeologist as in many cases they determine 
the locality of ancient battle-fields. Imperfect 
specimens are quite common, but fine perfect 
ones are extremely rare owing to their being so 
easily broken.

COLLECTING 
TPE SEN 
FOSSILS. 
By H. B. DERR. 
I took a collecting trip for fossils last fall 
through La Salle county, Ills. where the lime 
stone abounds with fossils of many species and 
think it may possibly interest some of the 
Naturalist readers who are making a study of 
Geology. The county is cut up in many places 
by deep ravines the bluffs on either side being 
of shaly limestone from 50 to roo feet in height 
in some localities. Iu the loose soil close to 
the stone I found large slabs of shells of the 
Productus species; they were in confused masses 
showing what immense pressure was brought 
to bear upon it when the lime stone was formed. 
The limestone of this locality corroborates the 
the writings of Geike and Dana who teach us 
that Limestone was made from the organic 
remains of shells, corals, crinoids and of the 
minute rhizopods. The absence of crinoid 
heads and presence of crinoid stems is probably 
due to the fact that the heads being more fragile 
were crushed to pieces. I came to this con- 
clusion from the fact that I found numerous 
pieces of crinoid heads.
