The governor’s plan was first to reduce the movements to a minimum; secondly, to obtain absolute uniformity of movement; thirdly, to secure by this absolute uniformity a perfect unconsciousness of effort of movement at all; in short, automatic movement; and all this in order that the continuity of glance, the look at the game, might not be interrupted for the merest fraction of a second. That glance was really the aim, the gun fitted itself to the gaze just as you thrust out your index finger and point, the body really did the work of aiming itself.

All the mind had to do was to effect the final adjustment of the black dot of the sight. Very often when the gun was thus brought up no such adjustment was necessary, it was already there, so that there was nothing to do but press the trigger. It then looked as if the gun touched the shoulder and was discharged instantaneously.

He was to look at the bird, to keep both eyes on it, to let his gun come to his eyes, still both open, adjust the dot and fire. There was no binocular trouble because he was never to stay to run his eyes up the barrels—that would necessitate removing his glance from the game, a thing strictly forbidden. Only the dot. He saw only the dot, and the dot gave no binocular trouble. The barrels were entirely ignored; the body had already adjusted them. Only the dot. The sight—this dot—is the secret of shooting.

The governor said if you shut the left eye you cannot retain your glance on the bird, the barrels invariably obscure it for a moment, and the mind has to catch itself again. He would not let Bevis take his eyes off it—he would rather he missed. Bevis was also to be careful not to let his right hand hang with all the weight of his arm on the stock, a thing which doubles the labour of the left arm as it has to uphold the weight of the gun and of the right arm too, and thus the muzzle is apt to be depressed.

He was not to blink, but to look through the explosion. Hundreds of sportsmen blink as they pull the trigger. He was to let his gun smoothly follow the bird, even in the act of the explosion, exactly as the astronomer’s clockwork equatorial follows a star. There was to be continuity of glance; and thus at last he brought down his snipes right and left, as it seemed, with a sweep of the gun.

The astronomers discovered “personal equation.” Three men are set to observe the occultation of a satellite by Jupiter, and to record the precise time by pressing a lever. One presses the lever the hundredth of a second too soon, the second the hundredth of a second too late, the third sometimes one and sometimes the other and sometimes is precisely accurate. The mean of these three gives the exact time. In shooting one man pulls the trigger a fraction too soon, another a fraction too late, a third is uncertain. If you have been doing your best to shoot well, and after some years still fail, endeavour to discover your “personal equation,” and by correcting that you may succeed much better. It is a common error and unsuspected, so is blinking—you may shoot for years and never know that you blink.

Bevis’s personal equation was a second too quick. In this, as in everything, he dashed at it. His snipes were cut down as if you had whipped them over: his hares were mangled; his partridges smashed. The dot was dead on them, and a volley of lead was poured in. The governor had a difficulty to get him to give “law” enough.

He acquired the mechanical precision so perfectly that he became careless and shot gracelessly. The governor lectured him and hung his gun up for a week as a check. By degrees he got into the easy quiet style of finished shooting.

The two learned the better and the quicker because there were two. The governor went through the same drill with Mark, motion for motion, word for word. Then when they were out in the field the one told the other, they compared their experiences, checked each other’s faults, and commended success. They learned the better and the quicker because they had no keeper to find everything for them, and warn them when to expect a hare, and when a bird. They had to find it for themselves like Pan. Finally, they learned the better because at first they shot at anything that took their fancy, a blackbird or a wood-pigeon, and were not restricted to one class of bird with the same kind of motion every time it was flushed.

Long before trusted with guns they had gathered from the conversation they constantly heard around them to aim over a bird that flies straight away because it usually rises gradually for some distance, and between the ears of the running hare. If the hare came towards them they shot at the grass before his paws. A bird flying aslant away needs the sight to be put in front of it, the allowance increasing as the angle approaches a right angle; till when a bird crosses, straight across, you must allow a good piece, especially if he comes with the wind.
