"And now," said the Baron, "to our fireworks!"

Herr Bettermann answered with the scowl-like contraction of the brows which he used in place of a nod.

"All right," he said. "Stand away from the front of the thing, will you? You know yourselves the kind of stuff you've buried yes? Also, los!"

The old baron had stepped back to Herr Haase's side; as the young man put his hands to the apparatus, he crisped himself with a sharp intake of breath for the explosion. A switch clicked under the young man's thumb, and he began to move the machine upon its pivot mounting, traversing it like a telescope on a stand. It came round towards the fresh yellow mounds of earth which marked Herr Haase's excavations; they had an instant in which to note, faint as the whirring of a fly upon a pane, the buzz of some small mechanism within the thing. Then, not louder than a heavy stroke upon a drum, came the detonation of the buried cartridges in the first hole, and the earth above them suddenly ballooned and burst like an over-inflated paper-bag and let through a spit of brief fire and a jet of smoke.

"Ach, du lieber" began the Baron, and had the words chopped off short by the second explosion. A stone the size of a tennis-ball soared slowly over them and plopped into the water a score of yards away. The Baron raised an arm as if to guard his face, and kept it raised; Von Wetten let his eyeglass fall, lifted it in his hand and held it there; only Herr Haase, preserving his formal attitude of obedient waiting, his large bland face inert, stood unmoved, passively watching this incident of his trade.

The rest of the holes blew up nobly; the last was applauded by a crash of glass as one of the upper windows of the house broke and came raining down in splinters. The lean young man swore tersely. "Another window!" he snarled. The Baron lowered his arm and let his breath go in a sigh of relief. "That is all, is it not?" he demanded. "Gott sei Dank I hate things that explode. But I am glad that I saw it, now that it is over, very glad indeed!"

There was a touch of added color in the even pink of his face, and something of restlessness, a shine of excitement, in his eyes. Even his voice had a new tone of unfamiliar urgency. He glanced to and fro from Herr Wetten to Herr Haase as though seeking someone to share his emotion.

Bettermann's thin voice broke in curtly. "It isn't over," he said. "There's the stuff he" with a glance like a stab at Von Wetten "threw into the lake. Ready?"

"Ach!" The Baron stepped hastily aside. "Yes; I had forgotten that.
Quite ready, my dear sir quite ready. Haase, my good friend, I think
I'll stand behind you this time."

"Zu Befehl, Excellenz," acquiesced Herr Haase, and made of his solidity and stolidity a screen and a shield for the master-mind in its master-body. Herr Bettermann, bending behind his machine, took in the grouping with an eye that sneered and exulted, jerked his angular blue-clad shoulders contemptuously, and turned again to his business.
