Quick and clear Kit gave his orders.

"Knapp, stop tinkering those bolts about, and stand back till I give the word! Now, Blob, listen here!—Knapp and I are going through this door down the drain. You'll stand here with the lantern, and light us, d'you see?"

"Ah!" said Blob.

"You're not to stir, d'you see, boy?"

"Aw!" said Blob.

Kit gripped his arm, and looked into his round and dewy eyes.

"Half-way down the drain there's a hole, where the light comes in." He was articulating his words with the slow precision of one addressing a deaf man. Now if, after we've passed that hole, anybody should get down through it into the drain, then you're to slam the door—and bolt!…

"Now repeat my instructions."

Blob mooned and mowed, his eyes roaming the cellar.

"Repate moi ructions," he mumbled at last.
