74 Report of the President 



Considerable progress has been made in the preparation 

 of the great collection of Cretaceous dinosaurs from Alberta. 



In addition to the completed exhibits already 

 Preparation of noted a skeleton of the Horned Dinosaur 



inhibition and 

 Study Collections Monoclomus and one of an armored dinosaur, 



probably new, are being prepared, also"skulls 

 of five other large and remarkable dinosaurs, two with con- 

 siderable parts of the skeletons, and an incomplete skeleton 

 of a horned dinosaur in which a large part of the skin is pre- 

 served. A fine skull and jaws of a Tertiary mastodon have 

 been partly prepared, work has been continued upon the 

 series of skeletons of the " Clawed Ungulate " Moropus, and 

 a number of other specimens have been prepared for study. 



The greatest need of Vertebrate Palaeontology in the 

 Museum is adequate exhibition space for our unique collection 

 ■^ _, r of Upper Cretaceous dinosaurs. This can be 



Exhibition Space remedied only by providing an additional 

 exhibition hall to accommodate the Jurassic 

 and Lower Cretaceous dinosaurs, a considerable part of which 

 is at present withdrawn for lack of space while the remainder 

 occupies a large part of the present Dinosaur Hall, which should 

 be devoted exclusively to Cretaceous dinosaurs. 



The installation of metal racks and trays in the larg 

 dinosaur storeroom has relieved a serious and dangerous con- 



., . gestion in these collections, to which atten- 



New Installation . 1t , . 



of Study Collections tlon has been called in previous reports. 

 The new arrangement consists of three 

 large steel stacks with steel-framed trays for large bones, 

 replacing the old temporary arrangement of wooden tables, 

 and a series of fireproof wall-stacks for the standard wooden 

 trays. A movable elevator makes it practicable to shift 

 and handle the loaded trays. This installation will remove 

 all danger from fire, increase the accommodation of the store- 

 room about threefold and make every specimen readily acces- 

 sible and easily removable. When completed it will take care 

 of the present and prospective study collections of dinosaurs 

 for at least ten years. At present, two of the large stacks
