THE DEPARTMENT OF AGRICBLTURE undertook some time ago an in- 
vestigation of the problem of discovering what plants could be grown 
upon the arid regions of the southwest. Bulletin number six? gives a 
report of collections and notes made by Mr. G. C. Nealley in Texas, and 
y Prof. S. M. Tracy in Arizona, New Mexico, Nevada and Utah. About 
200 species were collected, upon which various notes of greater or less 
interest are given. The conclusion reached from the reports is: “We — 
may be assured that there are many which would prove useful in culti- — 
vation, and it is to be hoped that the experiment stations of the states 
embraced in the arid districts will give such a thorough trial.” Which —

THE FOURTH FASCICLE of Castillo’s I/ustrationes flore insularum maris fs 
Fucifici fulfills the promise of its predecessors. The ten lithographic 
plates are charming, while the text of the ten species is correspondingly 
elaborate. The species are all Composite, viz.: Erigeron, 2 species; Li- 
Ppocheeta, 5 species (3 of them new); Bidens, 3 species (1 new). 
THE SECTION of Vegetable Pathology of the Department of Agriculture 
has been giving special attention to the diseases of the grape. efin 
No.5* gives an account of the experiments in the application of ree 
liquid and dry fungicides, such as sulphatine, etc., the basis of all of which 
is sulphate of copper. The results are somewhat contradictory, but 
sufficiently accordant to show that the remedies, or preventives ra i

The bulletin shows a wide-awakeness and energy in this section which 
are highly commendable. It is to be hoped that Commissioner Colman — 
Wiil be able to secure an active and able successor for Mr. Scribner, whose 
administration has been most praiseworthy. — oe
