be that of typesetting only, which is about $13.50 per page. The actual cost of 
preparing cuts for all illustrations must be borne by contributors: the cost 
for full page plates from line drawings is ordinarily $12.00 each, and the full 
page half-tones, $18.00 each: smaller sizes in proportion. 
AUTHOR'S SEPARATES 
Reprints of articles may be secured by authors, if they are ordered at the 
time proofs are received for corrections. A statement of their cost will be
