“It’s that perfusser,” explained Mrs. Bijur. “I tole him that he’d hev ter stop experimentin’ ef it was goin’ ter smell us out o’ house an’ home this er way. Awful, ain’t it?”

“Well, it is rather strong,” admitted Mr. Dacre, as they took seats in the stuffy parlor, with its wax fruit under their glass covers, the imitation lace tidies on the backs of the stiff chairs, and the noisy, eight-day clock ticking away like a trip-hammer.

“What ever is the professor doing?” he inquired.

“’Sperimentin’,” sniffed Mrs. Bijur, smoothing out her apron.

“Must be experimenting with cold-storage eggs,” put in Tom.

“No,” rejoined Mrs. Bijur gravely, “it’s some sort of a ’splosive. I tell you, Mister Dacre, I’m terrible skeered. Reely I be. S’pose thet stuff ’ud go off? We’d all be blown up in our beds.”

“Unless you happened to be awake, ma’am,” answered Mr. Dacre.

“Ah, but he don’t ’speriment only at night,” was the rejoinder. “He’s off all day huntin’ bugs and nasty crawly things. It’s only at night he works at it, an’ I tell yer, I’ve got my hands full with them Soopendyke children. They’re allers a-tryin’ to git inter the perfusser’s laboratory—he calls it. If they ever did, dear knows what ’ud happen. The perfusser says that ef any one who didn’t understand that stuff was to meddle with it, it might blow up.”

“Good gracious!” exclaimed Mr. Dacre, with mock anxiety. “I hope the young Soopendykes are all safely accounted for.”

“I dunno. There’s no telling whar them young varmints will git ter,” was the reply. “They’re every place all ter oncet, and no place long tergither. Tother day I cotched one tryin’ ter git inter the laboratory. Crawlin’ over ther roof, he was, and goin’ ter drop inter ther window by a water pipe. Seems ter me thet they are just achin’ ter blow themselves up, and——Good land! Look at ’em now!”
