SPECIAL OFFERS TO NEW SUBSCRIBERS. 

For the year 1891 the subscription rate for the GroLoGIsT will 
remain at $3.50. Any old subscriber who remits that sum with 
the name of a new subscriber will be entitled to have his own sub- 
scription extended six months. The cost of the numbers for 1888, 
after January Ist, 1891, will be $3.50; those of 1889, $2.50, and 
of 1890, $2.50. New subscribers who remit to us cash in advance 
will receive all back numbers and the subscription for 1891, for 
$11.00, but this will debar them from the privilege of the follow- 
ing premiums. 
Any new subscriber who remits to us cash in advance may select 
from the following premium list, by which he will receive the se- 
lected book and the Gro.oaist at a considerably less rate than he 
could obtain both separately. These are special offers for this 
specific purpose, for which we have made favorable arrangements 
with the various publishers. The works here listed are such as 
every geologist would desire to have in his library.
