During the summer, Mr. P. R. Uhler and Dr. A. S. Packard, 
Jr., were temporarily attached to the survey, and made collec- 
tions of insects in Colorado. Dr. Packard investigated the rav- 
ages of the destructive grasshopper and other injurious insects of 
Colorado and Utah, with a view to the preparation of a report on 
the injurious insects of the Territories. He also discovered a new 
cave-fauna on the shores of Great Salt Lake, and investigated 
the Alpine insects of the Rocky Mountains. 
RECENT LITERATURE. 
Wrman’s Fresu-Warer Sueit-Mounps or THe St. Jouy’s River, 
Froriwa.!— This very valuable contribution to our knowledge of the 
archeology of North America is modestly asserted by its Jamented au- 
or to be “a record of what he has observed and a contribution to the 
knowledge of these ancient relics of a race which has long since passed 
away.” It certainly is all this and more, although “still very incom- 
plete,” — a fact which goes far to show how wide a field for exploration 
and study is open to those devoted to archeological pursuits.- The 
memoir opens with an admirably clear sketch of the characteristic feat- 
ures of the St. John’s River, followed by a general description of the 
mounds, forty-eight in number, the majority of which are found between 
mussel shells (Unios), as elsewhere these heaps are entirely formed of 
Unios, the other shells being either very scantily represented or alto- 
gether absent. Those here described “are in almost every case built on 
the banks of the river, resting either on one of the ridges of sand and

(I), forming the frontispiece to the memoir, illustrates the shell-mound 
at Old Enterprise, “From the presence of fire-places, ashes, calcined 
Shells, charcoal, and implements, together with the bones of edible ani- 
Mals and occasionally those of man, found at various depths from top to 
bottom, and the absence of everything which might have been made by 
A white man, it seems certain that these mounds were the accumula- 
tions by and the dwelling-places of the earliest . . . . inhabitants, dur- 
mg the successive stages of their formation.” As bearing upon the 
question of the antiquity of these mounds and their various contents of 
nman origin, Professor Wyman remarks “that the building of the
