librarian whose cloth-bound quartos are much handled will bear 
me out in this. 
There is no advantage in very large type: it is just as easy 
to read the long primer used in the bulletins of the United 
States Geological Survey as it is to read the pica of the mono- 
graphs. 
There is no advantage whatever to a working geologist or 
to a student for his books to have large pages, wide margins, 
or to be printed on unnecessarily thick paper. Such books are 
cumbersome and unwieldly in the library or laboratory without 
an abundance of table room, and altogether out of the ques- 
tion for the field. 
Small books will serve equally well the man in the office 
or in the field, in camp or on horseback. The taking of books 
into the field should be encouraged; our laboratory is there, 
and there is no other place in which a book can render such 
lively service.
