388 Recent Literature. [ June; 
the work has been done is expressed in the statement that “ we 
have been able to publish each year reports of the work done the 
preceding year, an achievement which is believed to have been 
seldom accomplished in the history of Geological Surveys.” The 
report states that two additional years will be requisite for the 
completion of the Survey, for which an appropriation of $100,000 
is asked. On this we remark, that this request is a very modest 
one so far as the time required i is concerned, and is probably 
made with the view of representing the survey in as economical 
a light as possible. The unfinished tract includes the most diffi- 
e 
region reported as finished, could not Be, further elaborated. 
with advantage to all the interests concerned. Again, the impor- 
tant department of palæontology has received little attention from 
the Survey, the only work so far done relating to the plants of the 
coal-measures. There should surely be complete monographs of 
the plants of other horizons, of the very numerous invertebrata 
and of the important remains of the vertebrata found at several 
horizons and various localities within the State.
