Some work was also done on Red Deer river in connexion with a map 
that is being made, and a mammal jaw was collected from the Pale Beds. 
Mr. A. LaRocque spent some weeks collecting fresh water shells from 
a series of lakes in Algonquin park. 
Office and Laboratory Work 
Miss A. E. Wilson continued work on the catalogue of type fossils. 
W. A. Bell has made progress with a report on a Coal Measure flora. 
He was engaged from January to March, inclusive, in preparation of manu- 
script on the fossil floras of Nova Scotia. 
L. S. Russell has continued studies of the fossil mammals from Alberta 
and Saskatchewan, and guided the investigation of the invertebrate fauna 
of the Pakowki formation by R. W, Landes of Princeton University. 
C. M. Sternberg studied the dentary teeth of duck-billed dinosaurs 
and prepared a paper on “ The Systematic Position of Trachodon.” He 
began a study of a new species of Thescelosaurus. An exchange of verte- 
brate fossils was arranged with Amherst College. In the laboratory Mr. 
Sternberg and his staff mounted a Cretaceous turtle, finished the mount 
of a horse skeleton, and began the preparation of a dinosaur skull and a 
slab of rhinoceros skeletons. 
Exhibits 
Four good specimens of fossil insects in amber were added to the 
amber exhibit. 
A Cretaceous turtle, with splendidly preserved tail and feet, and a 
skeleton of the Pleistocene horse Equus scotti were placed on exhibit. A 
skeleton of the gazelle camel is ready to exhibit when space is available. 
About 20 mammal skulls were acquired by exchange with Amherst College. 
A large painting of the American mastodon by Mr. Lefebvre was placed 
in the vertebrate section of the exhibition. 
An exhibit relating to the work of the National Museum was pre- 
pared and installed at the Central Canada Exhibition in August. 
One hundred sets of fossils were prepared for the use of schools. 
As in previous years opportunities were supplied for visiting scientists 
to study the collections in the Museum. Professor Lull, Director of the 
Peabody Museum, spent about a week studying the dinosaur collections.
