Hofferman pressed a bell. An orderly appeared.

"Ask Captain Muller to kindly step in here."

Almost at once Captain Muller entered, saluted, and remained standing at some distance from his chief.

"Take this arm-chair, Captain." Hofferman was amiable politeness itself. Dumoulin, rather scandalised that the colonel should encourage such familiarity in a subordinate, was on the point of retiring discreetly. The colonel made him sit down also.

Hofferman turned to Captain Muller.

"You come amongst us, Monsieur, at a sad moment. You know, of course, that you are Captain Brocq's successor? A most valuable officer, to whom we were greatly attached."

Captain Muller bent his head. He murmured:

"We were men of the same year, comrades at the school—Brocq and I."

Hofferman continued:

"Ah, well, you are to take on the work begun by Captain Brocq.... Now tell me, Captain, what importance do you attach to the orders regarding the roll-call, the mustering and distribution of the mechanics and operatives of the artillery in the various corps—from the point of view of mobilisation, that is?"
