No rule can be laid down with regard to the frequency of bowling changes, except the more the better. A bowler should never be kept on if he is not getting wickets, and if the batsmen are playing him with ease. It goes no way towards winning a match to bowl ten or a dozen short-pitched consecutive maiden overs. Directly the batsmen seem to have guessed the length and style of bowling it should be changed, if only for a few overs, while some new style is tried for a short time. If a long stand be made, every style of bowling should be quickly tried; thirty runs should never be allowed without a change of some sort, unless the bowling happens to be particularly puzzling to the batsman, and is being badly played. As regards the placing of the field, it has already been said that usually the bowler is best able to guess where his own bowling is most likely to be hit; but there are many things which a captain should recollect, as the suggestions of a captain in whom his bowlers place confidence are always accepted readily. He should keep his eye on short-slip, as this place is, especially on a fast wicket, the most important of all. There are more good batsmen dismissed at short-slip and the wicket, on good wickets, than at any other places. It is an extraordinary fact connected with short-slip that, unless he has had a great deal of experience, he is continually shifting his position; one over he will be standing fine and deep and the next square and near to the wicket. It is the captain’s duty, even more than the bowler’s, to see that this does not happen.
