BOTANY. 
Frank’s Agricultural Botany. — Nearly every art and profession 
gradually gathers to itself a special series of text-books in allied 
sciences. To those expounding that part of botany most useful to 
the student of agriculture is now added an English translation of the 
little manual of Professor Frank of Berlin. While the occasion for 
such a book may not be obvious at a first glance, its author enjoys a 
reputation in the field chosen which entitles his work to a place 
wherever scientific agriculture is taught. T. 
The Wisconsin Survey. — In common with most of the richer 
states, Wisconsin has at various times provided for the exploration 
of its natural resources, but for some years no appropriations had 
been made for the continuation of this important work until about 
two years ago, when, the matter having been taken in hand by 
the State Academy of Sciences, Arts, and Letters,’ a legislative 
appropriation was obtained for the prosecution of a new geological 
and natural history survey of the state. When it was learned that 
Professor Birge had been made director, it became evident that the 
work would be conscientiously and efficiently carried on in such a 
manner as to supply both scientific and economic results. The 
recent publication of the first two bulletins of the Survey ® justifies
