WINTER AND THE INSECTS.

For a number of years previous to 1878 we had in Pembroke but little or

no severe cold, owing to the prevalence of southeast, south, west, and

especially southwest winds. In many places, fuchsias that were left in

the ground for the entire year had not been frozen to the root within the

memory of man. Some of these plants had grown to be trees five or six

yards in height, and with a trunk the size of one's leg. Now, during the

same series of years, many insects that are common throughout the rest of

Great Britain did not cease to be rare with us, or rather were confined

to certain circumscribed limits. Thus, the Noctuellae, with the exception

of a few species abundant everywhere, were almost wanting, and I know of

no other country where the dearth of common species of nocturnal

butterflies was so great. But during the winter of 1878 there supervened

a radical change. Persistent winds from the northwest, driving back the

currents of warm air from the south, brought on an intense cold that

froze everything; or, when some variation occurred in them, clouds formed

and dissolved into a rain that immediately froze, so that the large roads

remained for weeks covered with a layer of rime from two to four inches

thick.

The winters of 1879 and 1880 were equally cold; we may even say that the

latter was the severest that had been experienced in fifty years. This

year the sea-sand, along with the ice and snow, formed a thick crust all

along the tide-line--this being something rarely seen along our coast.

The first of these three winters (1878-1879) killed all the arborescent

veronicas and a few sumacs. As for the fuchsias and myrtles, they were

frozen down to the level of the soil.
