Larch is quite free from fungus diseases but suffers to some 
extent from the larch-miner moth (Colephora laricella, Hbn.), whilst 
a species of mistletoe is very prevalent upon silver fir. 
The forests of Chur give employment to 50 labourers regularly 
and to 120 during the summer months, and they are pai 
4 francs to 54 francs a day of 10 hours. After the planting season 
is over many of these men are employed in roadmaking, 
idea appears to be general throughout the country that a good 
system of well-made roads is essential to the success of forestry and 
wherever roads can be made slides are being abandoned in their 
favour, although the initial expense of roads is very heavy. Within 
e last few years 50 miles of forest roads have been made by this 
one commune. These are said to have cost about 20 francs per 
lineal metre. Of the expense the town has borne 70 per cent., the 
canton 10 per cent., and the state 20 percent. The comparatively 
small proportion borne by the canton is probably due to the fact 
that most of the forest areas in the canton of Graubunden are 
communal forests, very little being owned by the canton 
Engadine.—On Tuesday, July 22nd, a journey was made to 
St. Moritz and Pontresina. In this region the Swiss stone pine 
(Pinus Cembra, L.) and the common larch take the place of gir 
silver fir and other trees growing on the land drained by the Rhine 
and Rhone. Spruce is still seen but it is very small and does not 
grow sufficiently rapidly to make it a commercial success. Between 
the elevations of 6000 and 7000 feet larch and P. Cembra attain a 
considerable size and several successive larches girthed 10 feet, 8 feet, 
9 feet 5 inches, and 5 feet 8 inches respectively at breast high, 
These trees were between 250 and 300 years old. In this ey ae
