By Director C. S. Sargent.

It is pleasant to note that the prospects of this becoming one of the most valuable institutions of the kind in the world, are drawing nearer. People who see nothing but the few score species in woods or nurseries generally, have but a poor idea of the number of trees and shrubs that are in the world, and might be introduced. In this report, Prof. Sargent tells how, if all the species and marked varieties of trees, hardy in Massachusetts, were set out with room for the final development of each, 1000 acres would not hold them all.

It seems to us that the whole country is interested in this work, and not merely Massachusetts, and it would be well if tree lovers generally were to get a copy of this report if possible, and study how they might aid in the work Prof. Sargent has at heart.
