THE Woops AnD TIMBERS OF Nort CAROLINA.— This is a com- 
pilation by P. M. Hale, from the botanical and geological reports of 
rs. Curtis, Emmons and Kerr, to which are added information 
obtained from the Census Bureau, with reports from the several 
counties. A recent visit shows great improvement in the business 
activity and condition of the State. The Agricultural Depart- 
ment, by its museum and timely, authoritative: publications like 
famous for its vast forests, and this hand-book is an interesting 
and valuable résumé of the characteristics and distribution of the 
forest trees of the State. The book owes its value largely to the 
original report of the Rev. Dr. Curtis printed in Emmon’s Re- 
port on the Geology of the State, and reproduced in full. 
A Boranist’s Vacation.1—A delightful little book from the 
pen of the genial Professor of Botany in the University of Penn- 
sylvania reaches us just as the annual longing for rest and recre- 
ation comes to every brain-worker. It is a sermon in the gospe 
of relaxation, and it is so well preached that every reader will 
want to get a boat and follow the sailor-botanist down and up and 
across the Chesapeake and Delaware bays. There is a good deal 
of botanical inspiration in the book, and it is well worth reading 
T Ek yi proposing to take a few week’s run on the water.
