The boys came across the pig, which was frightened and attempted to run.

After running a little, he would slip on the ice and slide and tumble over, and then gather himself up again and try once more.

There was a general shout and a general chase.

Poor piggy strove to elude his pursuers.
His own tail was a little slippery, so that if a boy caught it he did not hold it long.

The whole college, pretty much, engaged in the pursuit, which certainly seemed to be great fun.
