One of the very simple, yet clever and successful, combinations worked in this way has been for the line half to take his position outside the tackle, who immediately begins to edge out towards the end. This opens a gap between the opposing tackle and guard, for the tackle will naturally follow his man. This line half simply watches the centre, and as he sees the ball played goes sharply behind the tackle and through the opening. This play can be greatly aided by cleverness on the part of the tackle, who, to perform it to perfection, should edge out most cautiously, and with an evident intention of going to the outside of his man. He should also watch the centre play, and, most important of all, jump directly forward into his man when the ball is snapped. This will enable the half to take almost a direct line for the half, and with his flying start have more than a fair chance of spoiling the kick. The tackle must not be idle after his plunge, but should follow in sharply, because there will always be an opposing half protecting the kicker; and if the line half be checked by this man, as is not unlikely, the following tackle has an excellent opportunity by getting in rapidly. The tackle and half should alternate in their arrangement, neither one always going through first, and thus add to the anxiety and discomfort of the opponents. [Illustration: EVERETT J. LAKE.

The cardinal point to be remembered is, to be far enough apart so that a single dodge and one interference cannot possibly throw off both men.
