"Hey!" he cried, and jumped to his feet so suddenly that Everson started. Zenas pointed at the fire, his little black eyes dancing and his beard wagging with his excitement.

"Well?" queried Everson.

"Coal, my boy, coal! There's oodles of it here. All I've got to do is to rig up a kiln for the distillation of coal-tar oil, and I'll have the phenol. God knows, these beggars are handy enough in the gentle art of blacksmithing. Tell your red-headed master of ceremonies to give me a little help—say two hundred or two hundred and fifty of his armorers, till I get a few kilns in operation and build me a bank of Glover towers, and I'll show you a line of stuff that will beat all of the Fourth of July celebrations you ever saw. Picrates! Humph! I'll turn out a brand of melinite for you that will jar the back door of hell off its hinges—if I don't whiff us all to kingdom come while I'm at the stuff."

Oleric was summoned. The red captain turned over to Zenas Wright not two hundred, but nearer five hundred men, and the old university was straightway turned into a munitions plant, the stench and the fires of which ascended to heaven by day and by night.

"And bring me about all the fat you can find in the kingdom," directed Zenas. "I'll need it to mix with my nice little patty-cakes."

"You shall have it, Father Zenas," Oleric replied. "And it will not come amiss to make all that you can of this pastry. After the Kimbrian Wall is down, we may find some of it useful at the gates of Adlaz."

So interested did Zenas become in this new work of his that he scarcely stopped for meals, and he slept on a cot of skins beside his fire in the old laboratory. One day, as he labored among his test-tubes, the outer door opened, and a tall figure robed in furs strode across the room and stood beside him. Zenas looked up impatiently.

"Oh, Lordy, laddie!" he cried, his face lighting up. "It's good to see you on your feet again."

It was Polaris—still somewhat gaunt and tottery, but with a welcome color in his cheeks and a brightness in his topaz eyes that augured well.

"Aye, old friend, 'tis I," he answered. "While you do wear yourself thin in this place of many smells, and Everson rides his flesh off his bones, shall I then be doing nothing but to lie in a soft bed and dream the days away? I will have no more of it."
