the cycle of migration and all associated 
phenomena: the spring migration; the 
attainment of the far northern calving 
grounds and the birth of a new genera- 
tion; the formation of great aggregations 
of insect-tormented animals in summer; 
the rutting period and a traditional an- 
nual hunt by Indians; and finally, the 
I vicissitudes of the often harsh and haz- 
ardous northern winter. 
Caribou and the Barren-lands deals 
with North American caribou, and par- 
ticularly with three herds that tradition- 
ally make great annual migrations from 
winter ranges in the northern coniferous 
forests to calving grounds and summer 
ranges far north on the tundra. For his 
descriptive narrative of spring migration 
and calving, the author chose the Bath- 
urst herd of the central Canadian main- 
land as a subject. For his study of cari- 
bou in winter, Calef uses the Beverly 
herd, the next great herd to the east. 
While they are neighbors, sometimes 
even exchanging animals, those two 
herds are considered discrete because 
they consistently use separate and dis- 
tant calving grounds — Bathurst Inlet on 
the arctic coast and Beverly Lake in the 
central tundra, respectively. 
Having spent much of my time from 
1949 to 1959 following one or the other 
of those herds by foot, dog team, canoe, 
and aircraft, I can honestly say that 
reading Calef’s narrative was rather like 
going home after a long trip. Beautifully 
done! Where I disagreed with the text, it 
was usually on interpretation rather 
than observation. It would, after all, be a 
strange pair of field biologists who saw 
everything in the same light.

The original 1 to-foot “Age of Reptiles” mural in the Great Hall of the 
Peabody Museum took four and a half years to complete and won the 
artist. Rudolph F. Zallinger, a Pulitzer Prize. The mural depicts thirty 
dinosaurs in six successive eras of earth history. The 6o-foot “Age of 
Mammals" mural presents the fauna and flora of the Paleocene to the 
Pleistocene era. Beautiful full-color reproductions of these unique 
masterpieces are available in two sizes. The larger, deluxe format— over 
9 feet long— is a lithographic print on a heavy, durable paper. The 
smaller version (6 feet long) is printed on glossy paper. Illustrated 
guidebooks are available for each mural.
