164 Report of the Brown-Harvard Expedition. 



of economic value. Most of their results in this line were 

 of a negative nature. Probably the great mass of the 

 country would not repay further investigation. It contains 

 large quantities of iron ore, some copper, some mica, and 

 some asbestos. It is not probable that any of these could 

 be worked to advantage. Our conclusion was that the only 

 localities that would be worth prospecting further are the 

 vicinity of Nain, and some 300 square miles about Mugford 

 and Nachvak. In the former place precious labradorite 

 occurs, doubtless in other situations than those already dis- 

 covered. In the latter region the structure of the country 

 is such as to admit the possibility of other valuable finds. 

 Pure graphite has been discovered about Nachvak Bay (see 

 Daly, Geology of the Northeast Coast of Labrador, p. 234). 



(/) Oceanography. — Dr. Daly made studies of the 

 Labrador current; sounded and charted Nachvak Bay, find- 

 ing it a typical fiord, no fathoms at the deepest part, and, 

 therefore, the deepest measured bay in Labrador; and made 

 almost daily observations of the temperature and salinity of 

 the sea-water at different depths. Among his results were 

 the determination of a temperature of 29.6° F. at the bot- 

 tom of the Straits of Belle Isle, and of 29° F. in the depths 

 of Nachvak Bay. These studies were carefully made and 

 will be valuable; but their results have not yet been su^- 

 ciently computed for any report upon them at present. Be- 

 sides their value as mere oceanographic data, they also fur- 

 nish material to some extent for study of conditions of life 

 among the cod, a matter of practical importance in which 

 Dr. Daly was largely interested. 



(k) Geology. — Dr. Daly was a tireless worker in this 

 field. He devoted attention to many different lines of study,
