Of other birds which are becoming scarcer year by year in England, the kingfishers are not uncommon in these parts; you will often see the brilliant little fellow dart past you as you walk by the stream in summer. Water-ousels or dippers are scarce; we have seen but one specimen in the last three years.
In September, as you walk over the fields, the Cotswolds are seen at their best. Somehow or other a country never looks so well from the roads as it appears when you are in the fields. The man who prefers the high road had better not live in the Cotswolds; for these roads, mended as they are with limestone in the more remote parts of the district, become terribly sticky in winter, while the grass fields and stubbles are generally as dry as a bone. There is but a small percentage of clay in the soil, but a good deal of lime, and five inches down is the hard rock; therefore this light, stony soil never holds the rain, but allows it to percolate rapidly through, even as a sieve. When the sun is hot after a frost the ploughs "carry" certainly, but this is because they dry so quickly; they seldom remain thoroughly wet for any length of time. Consequently, in hunting, the feet of hounds, horses, and even of foxes pick up the sticky, arable soil, instead of splashing through it, and scent is spoiled thereby. Doubtless the lime in the soil adds to its stickiness. It is amusing to watch a fox "break" covert and make his way over a plough which "carries": he travels very badly; we have seen him fail to jump a sheep hurdle at the first attempt. Fortunately for the fox, the hounds are also handicapped by these conditions, and scent is wretched. This might appear at first sight to show that the scent of foxes is chiefly given off from their feet. We can recall few occasions on which a plough that "carried" held a "burning scent." But little though we know of the mysteries of "scent," it is generally agreed that the "steaming trail" emanates chiefly from the body and breath of a fox, even though on certain days there is no evidence of any scent, save on the ground. It is probable, however, that on light ploughlands evaporation is so great when the sun is shining (unless the wind is sufficiently cold to counteract the heat of the sun and prevent rapid evaporation) that all scent from the body and breath of the fox, save that which happens to cling to the ground, is borne upwards and lost in the upper air. The hounds therefore have to fall back on whatever scent may remain clinging to the soil, those occasions of course excepted when the great density or gravity of the air prevents scent from rising and dispersing, and causes it to hang breast high.
After some years of careful experiment with the hygrometer and barometer, and after an intricate investigation of scent (that mysterious matter which is given off from the skin and breath of foxes), I have come to the conclusion that if we could get an Isaac Newton to "whip in" to a Tom Firr for about a twelvemonth, we might very likely come to know all about it. In standing on ground whereon "angels fear to tread," I am fully aware that I speak as a fool. But let me state that it is on the barometer that I now place my somewhat limited reliance on a hunting morning, and not on the hygrometer, on the weight of the column of air on a given point of the surface of the earth, rather than on the state of the evaporations, the relative humidity, and the dew point. And I have noticed that the best scenting days have been those when the thermometer has given readings from 38º up to 46º Fahrenheit in the shade. A high and steady glass, an almost imperceptible east or north-east wind, with the ground soaked with moisture and no frost during the previous night, is the only combination of conditions under which scent on the grass is a moral certainty. On the other hand, a low and unsteady glass, a warm, gusty south or west wind, with a hot sun, following a frost, or a day with cold showers, with bright, sunny intervals, or during the afternoon (but not always the morning) before a storm of wind or rain,--such are the conditions which make so many of our attempts to hunt the fox by scent a miserable farce; yet even on these days hounds may run during some part of the day. When the barometer is thoroughly unsettled there may be light local currents, perfectly imperceptible to man, yet felt by cows and sheep--currents created like winds by a variation of temperature in different parts of any given field, and which will scatter the scent and spoil the sport. These currents, rapid evaporation combined with a lack of steady atmospheric pressure, and that sticky state of soil which on ploughed land invariably follows a frost, and in a lesser degree affects grass, causing a fox to take his pad scent on with him (all the particles that do not cling to the ground having been diffused and lost in the air),--these are the curses of modern hunting fields and the chief causes of bad scenting days.
After September is past the shooting man will not get very much sport on the Cotswolds, as far as the partridges are concerned, for they are not numerous enough to be worth driving; they soon become as wild as they can possibly be. On Hatherop and some other estates good partridge driving is enjoyed. The farmers are very fond of shooting them under a "kite,"--this, as it is hardly necessary to explain, is an artificial representation of the hawk. It is flown high up in the air at some distance ahead of the guns. The birds, seeing what they take to be a very large and savage-looking hawk hovering above them, ready to pounce down at a moment's notice, become frightened, and lie crouching in the hedges and turnips, until they almost have to be kicked up by the sportsmen. But when once they do get up they fly straight away, nor do they come back for a long time. This mode of shooting is all very well once in a way, but if indulged in habitually it scares the birds, driving them on to other manors. Not having seen it successfully carried out, we are not fond of the method, but there are good sportsmen in these parts who advocate it. Some maintain that this cannot be called a really sportsmanlike way of shooting partridges, though there is doubtless room for two opinions on the question.
Later on in the autumn, when November frosts begin to attract snipes to the withybeds and water meadows by the Coln, the unambitious gunner may often enjoy the charm of a small and select mixed bag.
Two of us went out for an hour last winter before breakfast, having been informed that a woodcock was lying in an ash copse by the river. We got the woodcock--a somewhat rara avis in small, isolated coverts on the hills; in addition, the bag contained one snipe, one wild duck, two pheasants, six rabbits, a pigeon, a heron, and some moorhens. Now this was very good sport, because it was totally unexpected. The majority of shooting people might not think much of so small a bag, but it must be remembered that the charm of this kind of shooting is its wildness. It seems rather hard to kill herons, but anybody who has tried to preserve trout will agree that herons are the greatest enemies with which the trout-fisher has to contend. One heron will clear a shallow stream in a very short time. When the floods are out, trout fall a ready prey to these rapacious birds. The kingfishers likewise have a very good time. The fish will gorge themselves with worms picked up on the inundated meadows, until they are so full that the worms actually begin falling out of their mouths. I picked several up last autumn which had been stabbed, I suppose, by a heron. They were unharmed, save for a small round hole, as if made by a bullet; there was no other mark on them. But when taken up, the worms came out of their mouths by the score! Kingfishers are carefully preserved, in spite of their destructiveness, but one must draw the line at herons.
Waiting for wild duck coming into the "spring" on a frosty night is cold work, but very good fun. They breed here in fair numbers, and fly away in August. But when the ground becomes "scrumpety," as the natives say, with the first severe frost, back they come from the frozen meres to their old home; and if one can keep out of sight (and this is no easy matter in December) many a shot can be obtained in the withybeds by the river. Teal and widgeon may be shot occasionally in the same manner.
Sometimes, when you are upon the hills with Tom Peregrine, the keeper, trying to pick up a brace or two of partridges for the house, he will suddenly say, "Quad down!" then, throwing himself on to his hands and knees in breathless anxiety, he will begin whistling for "all he knows." You imitate him to the best of your ability, and soon, if you are lucky, an enormous flock of golden plover flash over you. Four barrels are fired almost instantaneously, and the deadly "twelve-bore" of your companion is seldom fired in vain.
Green plover, or lapwings, are numerous enough on the Cotswolds. They are wonderfully difficult to circumvent, nevertheless. You crouch down under a wall, while your men go ever so far round to drive them to you; but it is the rarest thing in the world to bag one. Their eggs are very difficult to find in the breeding season. It is the male bird that, like a terrified and anxious mother, flies round and round you with piteous cries; the female bird, when disturbed, flies straight away.
