46 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 59 
including Mr. Hollister, and Mr. J]. H. Riley of the Division of Birds 
in the National Museum. Assembling at Edmonton, Alberta, Canada, 
early in July, 1911, they proceeded on the Grand Trunk Railroad to 
the end of the line where they took pack horses and penetrated the 
Mount Robson region. The land surveyed included the territory 
lying about this mountain in the heart of the Canadian Rockies, 
comprising the most rugged and broken country imaginable. Amid 
this wonderful scenery Mount Robson rises in titanic outline, the 
highest peak in Canada, probably between 14,500 and 15,000 feet 
high, and surrounding it for a distance of 50 miles in all directions 
lies the field of the survey. In this wild and unclaimed country the 
party of naturalists remained nearly four months, protected by 
special permits from the Canadian government. The natural history 
work was divided up, Mr. Hollister and Mr. Riley collecting the 
birds and small mammals, while the other two collectors hunted big 
game. The collection includes some 900 specimens of birds and 
mammals, the latter being of all kinds from tiny shrews to caribou 
and bears. One enormous grizzly bear was obtained by a fortunate 
shot. Much fine material for exhibition groups was secured, includ- 
ing a series of caribou, mountain goats, mountain sheep, beavers, and 
many varieties of smaller animals. As already mentioned, large 
numbers of plants and insects were also collected. All this material 
was turned over to the National Museum. 
INVESTIGATIONS OF MAINE SHELL-HEAPS 
While the above explorations were being carried on in various 
regions, a number of minor investigations were undertaken along 
the Atlantic seaboard. One of these had for its purpose the as- 
sembling of animal remains from the shell-heaps of the Maine 
coast, eastward from Penobscot Bay, in order to ascertain whether 
the fauna at the time the heaps were accumulating was different from 
that now existing in the same region, a question which seemed to 
demand attention from the fact that an extinct species of mink had 
been found in some of the heaps. The work was carried on by 
Dr. F. W. True in the summer of 1910, in continuation of investi- 
gations of preceding years, the field of operations extending from 
Sargentville, opposite Deer Isle, to Harriman’s Point in Bluehill Bay. 
Large numbers of bones and teeth of mammals and other vertebrates 
were obtained, as well as fragments of pottery and other objects of 
human workmanship. A part of this territory was explored some years 
ago by Major J. W. Powell and Mr. Frank H. Cushing of the Bureau
