"As is well known, the mosquito-pest is by no means confined to the tropics or even to temperate regions. The stories which the from and other Alaskan localities tell of the abundance and ferocity of Alaskan mosquitoes, are hardly to be matched by any mosquito story which I have heard, historical or otherwise. Many of my friends in the and the who have formed members of summer parties for survey work in Alaska, have come back to this country with a much stronger idea of the importance of the practical study of insects than they had when they started, their acquaintance with mosquitoes having become so intimate and their knowledge of their ferocity having reached such a pitch that the first question which they ask on returning is: "If I have to go up there next summer, what under the sun can I do to keep from being bled to death by mosquitoes?" They state that they never experienced or even imagined anything in the mosquito line quite equal to those found in Alaska. Mr. W. C. Henderson, of Philadelphia, says, concerning Alaskan mosquitoes, "They existed in countless millions, driving us to the verge of suicide or insanity.""
