ed to me that
_that_ was the way to stop tackle-back!"

"That? What?" asked Mills, looking puzzled.

"Why, the bag of potatoes act," laughed Sydney. "I jumped up, lighted
the gas, got pencil and paper and went back to bed and worked it out.
And here it is."

He drew a carefully folded slip of paper from his pocket and handed it
across to Mills. The diagram, just as the head coach received it, is
reproduced here.

Mills studied it for a minute in silence; once he grunted; once he
looked wonderingly up at Sydney. In the end he laid it beside him on
the desk.

"I think you've got it, Burr," he said quietly, "I think you've got it,
my boy. If this works out the way it should, your nightmare will be the
luckiest thing that's happened at Erskine for several years. Draw your
chair up here--I beg your pardon; I forgot. I'll do the moving myself."
He placed his own chair beside Sydney's and handed the diagram to
him. "Now just go over this, will you; tell me just what your idea is."

Sydney, still excited over the night's happenings, drew a ready pencil
from his pocket, and began rather breathlessly:

"I've placed the Robinson players in the positions that our second team
occupies for the tackle-tandem. Full-back, left tackle, and right half,
one behind the other, back of their guard-tackle hole. Now, as the ball
goes into play their tandem starts. Quarter passes the ball to tackle,
or maybe right half, and they plunge through our line. That's what they
would do if we couldn't stop them, isn't it?"

"They would, indeed," answered Mills grimly. "About ten yards through
our line!"

"Well, now we place our left half in our line between our guard and
tackle, and put our full-back behind him, making a tandem of our own.
Quarter stands almost back of guard, and the other half over here. When
the ball is put in play our tandem starts at a jump and hits the
opposing tandem just at the moment their quarter passes the ball to
their runner. In other words, we get through on to them before they can
get under way. Our quarter and right half follow up, and, unless I'm
away off on my calculations, that tackle-tandem is going to stop on its
own side of the line."

Sydney paused and awaited Mills's opinion. The latter was silent a
moment. Then--

"Of course," he said, "you've thought of what's going to happen to that
left half?"

"Yes," answered Sydney, "I have. He's going to get most horribly
