As to protection, it is varied enough in all conscience, and always theoretically perfect. A head-net falling well down over your chest, or even tied under your arm-pits, is at once the simplest and most fallacious of these theories. It will keep vast numbers of flies out, to be sure. It will also keep the few adventurous discoverers in, where you can neither kill nor eject. Likewise you are deprived of your pipe; and the common homely comfort of spitting on your bait is totally denied you. The landscape takes on the prismatic colours of refraction, so that, while you can easily make out red, white, and blue Chinese dragons and mythological monsters, you are unable to discover the more welcome succulence, say, of a partridge on a limb. And the end of that head-net is to be picked to holes by the brush, and finally to be snatched from you to sapling height, whence your pains will rescue it only in a useless condition. Probably then you will dance the war-dance of exasperation on its dismembered remains. Still, there are times--in case of straight-away river paddling, or open walking, or lengthened waiting--when the net is a great comfort. And it is easily included in the pack.
Next in order come the various "dopes." And they are various. From the stickiest, blackest pastes to the silkiest, suavest oils they range, through the grades of essence, salve, and cream. Every man has his own recipe--the infallible. As a general rule, it may be stated that the thicker kinds last longer and are generally more thoroughly effective, but the lighter are pleasanter to wear, though requiring more frequent application. At a pinch, ordinary pork fat is good. The Indians often make temporary use of the broad caribou leaf, crushing it between their palms and rubbing the juices on the skin. I know by experience that this is effective, but very transitory. It is, however, a good thing to use when resting on the trail, for, by the grace of Providence, flies are rarely bothersome as long as you are moving at a fair gait.
This does not always hold good, however, any more than the best fly-dope is always effective. I remember most vividly the first day of a return journey from the shores of the Hudson Bay. The weather was rather oppressively close and overcast.
We had paddled a few miles up river from the fur trading-post, and then had landed in order to lighten the canoe for the ascent against the current. At that point the forest has already begun to dwindle towards the Land of Little Sticks, so that often miles and miles of open muskegs will intervene between groups of the stunted trees. Jim and I found ourselves a little over waist deep in luxuriant and tangled grasses that impeded and clogged our every footstep. Never shall I forget that country--its sad and lonely isolation, its dull lead sky, its silence, and the closeness of its stifling atmosphere--and never shall I see it otherwise than as in a dense brown haze, a haze composed of swarming millions of mosquitoes. There is not the slightest exaggeration in the statement. At every step new multitudes rushed into our faces to join the old. At times Jim's back was so covered with them that they almost overlaid the colour of the cloth. And as near as we could see, every square foot of the thousands of acres quartered its hordes.
We doped liberally, but without the slightest apparent effect. Probably two million squeamish mosquitoes were driven away by the disgust of our medicaments, but what good did that do us when eight million others were not so particular? At the last we hung bandanas under our hats, cut fans of leaves, and stumbled on through a most miserable day until we could build a smudge at evening.
For smoke is usually a specific. Not always, however: some midges seem to delight in it. The Indians make a tiny blaze of birch bark and pine twigs deep in a nest of grass and caribou leaves. When the flame is well started, they twist the growing vegetation canopy-wise above it.
In that manner they gain a few minutes of dense, acrid smoke, which is enough for an Indian. A white man, however, needs something more elaborate.
The chief reason for your initial failure in making an effective smudge will be that you will not get your fire well started before piling on the damp smoke-material. It need not be a conflagration, but it should be bright and glowing, so that the punk birch or maple wood you add will not smother it entirely. After it is completed, you will not have to sit coughing in the thick of fumigation, as do many, but only to leeward and underneath. Your hat used as a fan will eddy the smoke temporarily into desirable nooks and crevices. I have slept without annoyance on the Great Plains, where the mosquitoes seem to go in organized and predatory bands, merely by lying beneath a smudge that passed at least five feet above me. You will find the frying-pan a handy brazier for the accommodation of a movable smoke to be transported to the interior of the tent. And it does not in the least hurt the frying-pan. These be hints, briefly spoken, out of which at times you may have to construct elaborate campaigns.
But you come to grapples in the defence of comfort when night approaches. If you can eat and sleep well, you can stand almost any hardship. The night's rest is as carefully to be fore-assured as the food that sustains you. No precaution is too elaborate to certify unbroken repose. By dark you will discover the peak of your tent to be liberally speckled with insects of all sorts. Especially is this true of an evening that threatens rain. Your smudge-pan may drive away the mosquitoes, but merely stupefies the other varieties. You are forced to the manipulation of a balsam fan.
In your use of this simple implement you will betray the extent of your experience. Dick used at first to begin at the rear peak and brush as rapidly as possible toward the opening. The flies, thoroughly aroused, eddied about a few frantic moments, like leaves in an autumn wind, finally to settle close to the sod in the crannies between the tent-wall and the ground. Then Dick would lie flat on his belly in order to brush with equal vigour at these new lurking-places. The flies repeated the autumn-leaf effect, and returned to the rear peak. This was amusing to me, and furnished the flies with healthful, appetizing exercise, but was bad for Dick's soul. After a time he discovered the only successful method is the gentle one. Then he began at the peak and brushed forward slowly, very, very slowly, so that the limited intellect of his visitors did not become confused. Thus when they arrived at the opening they saw it and used it, instead of searching frantically for corners in which to hide from apparently vengeful destruction. Then he would close his tent-flap securely, and turn in at once. So he was able to sleep until earliest daylight. At that time the mosquitoes again found him out.
