To MAJOR D. R. CAMERON, R. A. 
Hf, M. North American Boundary Commissioner :-— 
Sir,—I have the honour to present herewith, my final Report of 
work in connection with H. M. North American Boundary Commission. 
In undertaking single-handed the care of Natural History work in con- 
nection with the Boundary Commission, it was obvious that in attempting 
too much it might happen that nothing should be well done. I therefore 
decided to give the first place to geology; and in that field to endeavour 
to work out as far as possible the structure of the country, and to make 
illustrative collections of rocks and fossils, rather than to amass large 
local collections, at the expense of general information. Such time as 
could be spared from the geological investigations, has been devoted to 
collection and work in other departments ; and in this Report the results 
are presented, elaborated in so far as the time at my disposal would allow, 
and supplemented also by several valuable notices of the collections in 
special departments, by gentlemen whose names are elsewhere stated. 
The field work, in extent, has directly covered a region, stretching 
from the Lake of the Woods on the east, to the Rocky Mountains on the 
west, and lying in the vicinity of the forty-ninth parallel, which here 
forms the International Boundary. In time it has extended over two 
seasons, those of 1873-74. Owing to the vastness of the region covered 
by the operations of the survey, much of the period actually spent in the 
field has been necessarily employed in more or less arduous, and often 
almost continuous travel. 

To yourself I am under great obligations for the facilities readily 
S granted for work in the department entrusted to me, and for the interest 
i. 
} 
, by you have taken in its progress. To all the officers of the Commission [
