I'.platid in the foreground, and on eacli day numerous s(|ualls of fine 

 snow or frozen mist would sweep over from Thompson Pass or 

 Bryce glacier. 



I do not know the origin of the names of Rice and Bryce. hut it 

 is prohahle that the mountains were named in ln^nor of Sir Cecil 

 Arthur Spring-Rice and Lord James l^)ryce. 



As the result oi unfavorahle weather not more than one-third of 

 the work planned was completed when the late Septemher snow drove 

 us back to the railroad. The morning we hroke camp to go to Lake 

 Louise Station the horses were pawing away the snow to get at the 

 grass beneath (tig. 2^). and the snow was very beautiful on the trees 

 and along the stream below camp (fig. 24). The trail was obscured 

 by it and to make matters more complicated, snow driven h\ a strong 

 east wind beat into our faces during the seven hours march. The 

 next day the sun came out and the storms were forgotten except for 

 the wonderful snow scenes along the trail down the Pipestone River. 



The Commissioner of the Canadian National Parks, Hon. J. ].V 

 Harkin, and the members of the Parks Service in the field, from 

 Superintendent to Park A\'arden. were most helpful, and the same is 

 true of the officials and employees of the Canadian Pacific Railwav. 



PALEONTOLOGIC.\L FIELD-WORK IX THE UNITED STATES 

 Field-work by the Department of Geology of the U. S. National 

 jNIusetnu diu'ing 1921 was carried on by three members of the Division 

 of Invertebrate and \'ertebrate Paleontology. 



Dr. R. S. Bassler, Ciu'ator oi the Division of Paleontologv, in 

 cooperation with the Geological Stirvey of Tennessee spent the 

 month of July in field-work in the Central Basin of that State, where 

 he was occupied in collecting geologic material and in mapping and 

 studying the economic resources of the Franklin cjuadrangle in 

 Williamson County, south of Nashville. This area of about 250 square 

 miles is of economic interest, on accomit of phosphate and oil shale 

 possibilities. It is also classic ground for the paleontologist because 

 of the numerous outcro])s of Ordovician and later Paleozoic forma- 

 tions which afi^ord a wealth of fossils. During the course of the 

 mapping. Dr. Bassler was able to collect a considerable number of 

 these fossils needed in the museum study series and was also fortu- 

 nate in securing several large exhibits illustrating various geological 

 phenomena. Among the latter is a large mass of limestone composed 

 entirely of the dismembered calices and columns of a large species of 

 crinoid or sea lily in which the individual fragments are perfectly
