Some men have a special gift for marking a bird that is down, while others never know where the bird fell within half an acre. But marking is only a matter of training the eyes, and anybody may learn the trick: in time the eyes accurately note what they see almost unconsciously. The sportsman cannot be too accurate in marking the fall of a bird. The great thing is to take a good line--an imaginary line drawn from the eye to the place where the bird fell: if at a far distance, the actual spot will be nearer in reality than it seems. The accustomed eye finds points which mark the line, if not the very spot, where the bird has fallen--a spray of charlock flower, a thistle-stem, or a tinted leaf. When a bird falls at a distance it is helpful to take some prominent object in front and behind to mark the line--such as a gap and a sapling in opposite hedges. A sportsman who is a master of the art of marking knows where to come upon each bird he shoots singly; and when he scores a brace he knows all about the second bird. Often he knows much more about the first bird than those who have nothing else to do but to mark. The usual rule is for the attendant to mark the first bird that falls and the shooter the second. With two men to mark one bird it should be quite easy to find the place. The bird will be within a yard of where the two imaginary lines intersect. A common mistake made by sportsmen is to suppose that because they have fired at a bird coming towards them it must have fallen in front of them: more probably it has fallen several yards behind, especially if it be a bird brought down by the second barrel. It is not easy to mark the place where a covey pitches. On seeing the birds suddenly lower their line of flight, a sportsman may suppose they have alighted, unless he still keeps a watchful eye on them, for birds often lower their flight when they have crossed a hollow or a valley, and then skim on low over the crest of the hill. However, when birds lower their line of flight, after flying some distance, it is a sign that they contemplate settling. * * * * * The Keeper's Dogs
