"You're quite a lecturer, Bobbie," he said. "Wait until I get back home and astonish my father with all this knowledge. I'll make his eyes stick out."

Van broke into hearty laughter at the thought. Then, as he started to walk on he gave a shout of dismay.

"Hold onto me, Bob," he cried. "I can't move. While I've been standing here listening to your words of wisdom I've been sinking deeper and deeper into your old yellow mud until now I can't stir. I can't—upon my word. My feet are in perfectly solid. You can laugh if you want to, but you've just got to pull me out, that's all. Help! Help! To the rescue. I shall disappear in another minute. David will never see his rubber boots again."

"Of course you can get your feet out," was Bob's scornful retort.

"Cross my heart I can't. Honest, Bobbie," protested Van. "I've got into a quicksand or a quagmire or something. Look at me. I'm up to my knees now, and if you don't hurry you'll see nothing of me but my collar. I saved your life yesterday; you might do the same for me to-day."

But Bob was too convulsed with amusement to offer aid; instead he stood on a large rock at the roadside and laughed immoderately.

"Pull! Pull!" he cried to Van. "Why don't you pull?"

"I am pulling," Van answered. "But it does no good. I can't budge my feet. I never saw such mud in all my life. It must be yards deep. It sucks my boots right off. You'll have to help me."

"Not I! I know too well what would happen. It would be like Kipling's story of the Elephant's Child. Don't you remember, when the crocodile let go the nose of the little elephant how he suddenly sat down plop. I've no notion of being pulled into this mud hole when your rubber boots come to the surface. You'll have to get yourself out."

"You old heathen! It is not a straight game to fit me out with a pair of hip rubber boots miles too large for me and then sit and howl when you see me losing my life in them. Well, you needn't come into the mire if you don't want to, but you can at least be gentleman enough to pass me the end of that pole that is lying beside you," said Van.
