Now it was that Birch's experiences served us in good stead. I never knew a fellow more thoroughly cunning; he might have been a fox instead of a hare. Sometimes he made me run behind him and drop my scent on the top of his, and sometimes keep a good distance off, and let the wind scatter it as much as it could. When we came to a gap, instead of starting straight across the next field he would turn suddenly at right angles, and keep close up under the hedge half-way round before striking off into the open. Among trees and bushes he zigzagged and doubled to an alarming extent, so that it seemed as if we were losing ground every moment. So we should have been if the chase had been by sight instead of by _scent_; but that would have been against all rules. If the hounds were to see the hares twenty yards in front of them, and the scent lay half a mile round, they would be bound, according to our rules, to go the half-mile, however tempting the short cut might seem. It was after a very wide circuit, ending up on the top of a moderate rise, that we first caught sight of our pursuers. As they were a full six minutes behind us, we agreed to sit down under cover for a minute and watch them. At that moment they had evidently lost the scent, and were ferreting about among some low trees and bushes in search of it. We saw the flag of the whipper-in marking the spot where it was last visible, and round this, on all sides, the hounds were exploring busily in search of the "new departure." Then, presently, came a cry of "Forward!" and off they all started in our direction; and as the scent after that seemed to lie pretty clear we considered it high time for us to resume our flight. So we made off again, and being refreshed by our brief halt, made over a couple of ploughed fields, which Birch suggested "would make a few of the hounds look foolish"; and so on till we reached the first water we had encountered since the start. This was a trout-stream, well known to some of us who were fond of fishing--nowhere more than half a foot deep, and in some places easily passable, dry shod, on stepping-stones. Birch, however, avoided these, and boldly splashing into the stream over his ankles, bade me follow. "We'll soon dry up," he said, "and this will gain us a minute or two." Instead of going straight across, the wily hare began to paddle up the middle of the stream for twenty or thirty yards, and, of course, in so doing our scent was soon drifted away down the current. So we flattered ourselves, when we at last did make the opposite bank, that our pursuers would be puzzled for a minute or two to know what had become of us. After a further quarter of a mile we thought we might venture to take another brief halt on the strength of this last manoeuvre. We were unable to do so where we could command a view of the hounds, but as we reckoned we had at least gained three minutes, we felt we could quite afford to take it easy for that length of time.
