Little Jim felt the force of the observation, and made what we may call a mighty effort--considering that he was such a mite of a thing--to restrain himself. His heroism was rewarded, for, in less than half an hour, the engine came rattling back again, its services not having been required! The fire had occurred close to the fire-escape, of which one of the men of that station had the charge that night. He had run to the fire with his escape at the first alarm, and had brought to bear on it the little hand fire-engine, with which all the escapes are now provided. At that early stage in the fire, its little stream was more effectual than the flood from a powerful "steamer" would have been at a later period. The consequence was that the fire was got under at once, and, as we have said, the engine was not required. "Wirtoo," observed the Bloater, sententiously, "is its own reward." He pointed to the returning engine, and looked at Little Jim with solemnity; whereupon Jim displayed all his teeth, nodded approval of the sentiment, and--"sk!" "Little Jim," continued the Bloater, shaking his head gravely, "they do say--them as knows best, or thinks they does, which is all the same-- that there's wit in silence; if so, it appears to me that you tries to be too witty at times." "I dun know, Bob," replied Jim, with a meditative look, "much about wit bein' in silence. I only wish there was wittles in it. Oh! wouldn't I 'old my tongue, just, till I was fit to bust!" "But there ain't wittles in it, Jim, nor nothin' else worth 'avin', so don't try it on too much to-night. You see, I'm a bit down-'earted about the thoughts o' this 'ere black business, an' feel the want of a cheerin' word now and agin to keep up my droopin' spirits, d'ye see; so don't stand grinnin' there like a Cheshire cat, else I'll--" The Bloater terminated the sentence in action, by squeezing Little Jim's cap over his eyes. He was still engaged in this act of pleasantry when Mr Sparks and his friend Jeff appeared on the other side of the street. They walked smartly past the door of the fire-station, which was shut by that time, the men having retired to their various domiciles for the night, with the exception of the two on night duty. They stopped at the corner of the street, looked back, and stood as if conversing casually with each other. Meanwhile, the two boys shrank out of sight, and gazed at them like weasels peeping out of a hole. The street, being a small back one, was quite deserted at that hour. After talking in low tones for a few seconds, and making sure, as Jeff said, that the coast was clear, the incendiaries shrunk round the corner and disappeared. "Now, Jim," whispered the Bloater, "they've gone to Number 5; let's foller."
