INSECTS OF THE FOREST.

forms. Brilliant green and golden Bnprestids may be seen 
sunning themselves on the trunks of the trees, and the olive 
green Monohammus beetles so destructive to pines flying 
among the trees or emerging from their holes in the trunks. 
The Urocerus, a saw-fly like the Tremex, one of the charac¬ 
teristic insects of pine forests sails around in its circling 
flight, and pine weevils and timber beetles open their wings 
in the heat of the sun. The weeds, nearly all of European 
origin, crowd out the aboriginal inhabitants, and with their 
rank growth hedge about the cabin. With them have ar¬ 
rived the usual proportion of imported insects, but most 
characteristic of the northern forests are the Arthemis but¬ 
terfly, the banded Buprestis, the pine weevils, the russet 
geometrid moth and others. 
If the destruction of forests goes on as rapidly as at pres¬ 
ent all these forest insects will soon have lost their occupa¬ 
tion. We shall then have to plant new forests, as they have 
and are doing in portions of northern Italy, in Austria, Ger¬ 
many and Great Britain. When this is done and the young 
trees are growing in extensive plantations, the danger aris¬ 
ing from the ravages of destructive insects will be very 
great. As in Europe, we shall have to make chairs of for¬ 
estry in our agricultural colleges, and appoint commissioners 
of forests. Then, if not at the present day, a thorough and 
practical knowledge of forest 'insects will be one of the 
guarantees to success in the cultivation of trees. At pres¬ 
ent Germany leads the civilized world in the intelligent care 
of her replanted forests. How carefully the trees are nur¬ 
tured, how intelligently their diseases are studied, and with 
what pains the habits and forms of the destructive insects 
are described and drawn, is well known. The elaborate and 
beautifully illustrated works of the ;iate Dr. Ratzeburg have 
made his name famous, and they form a perpetual witness to 
the intelligence and forethought of the people who encourage 
by their patronage the publication of such expensive and
