"I've certainly lost mine," rejoined Derek.

"That's base ingratitude," protested his chum, "considering I told the messman to keep it hot. I say, you guys!" he added, addressing the other five or six occupants of the ante-room. "Daventry's raising a moan about his grub. What's the penalty?"

The next instant a rolled-up flag came hurtling at Derek's head. It was the signal for battle. There was ammunition in plenty, for nearly fifty rolled signal-flags that were left over after decorating the mess were lying on the table in the hall.

Grabbing half a dozen missiles, Derek ran upstairs; Kaye, out of loyalty, joined him, and Dennis threw in his lot with the weaker side. Ensued a battle royal. From the first-floor landing bundles of tightly-rolled bunting came flying down with tremendous force, while the attackers of the ground-floor retaliated with similar missiles, until the air was stiff with a hurtling galaxy of signal-flags.

For a time it seemed as if weight of "metal" and superior numbers would prevail. Already the attackers were half-way up the stairs, dauntlessly facing an overhead fusillade, when the youthful Adjutant was seized with a "toppin' brainy idea".

Grasping one of the filled fire-buckets, he balanced it on the balustrade, then, awaiting his opportunity, poured the cold contents upon the heads of his opponents. Kaye and Derek, fired by Dennis's example, followed suit, and the attack melted away.

"Gosh!" exclaimed Dennis, "won't little Wells be in a horrible tear when he finds his precious signal-flags used like this?"

It was indeed a scene of chaos. Partly unfolded the flags lay everywhere. Pools of water lay in the hall, while a considerable quantity had made its way down into the basement to the discomfiture of the batmen.

"It's merely a change in the day's occupation," declared Kaye. "Blame Daventry; he must have a safety-valve to let off superfluous energy after having tried his level best to provide the fishes with roast meat for Christmas."

"Who's turning in?" asked Derek, stifling a yawn. "It's ten o'clock, and I've been at it since six this morning."
