He was overjoyed when the college organized Thursday afternoon visits to factories. He chose his companions in advance, sometimes compelling them to give up a game of tennis. Krebs was one of them. For Georges the visits to the Puteaux and Dion-Bouton factories were a feast of which he was often to speak later. He went, not as a sightseer, but as a connoisseur. He could not bring himself to remain with the engineer who showed the party through the works. He required more liberty, more time to investigate everything for himself, to see and touch everything. The smallest detail interested him; he questioned the workmen, asking them the use of some screw, and a thousand other things. The visit was too soon over for him; and when his comrades had already left, and the division prefect was calling the roll to make sure of all his boys, Guynemer as usual was missing, and was discovered standing in ecstasy before a machine which some workmen were engaged in setting up. "The opening weeks of the automobile and aviation exhibition were a period of comparative tranquillity for his masters, as Guynemer was no longer the same restless, nervous, mischievous boy, being too anxious to retain his privileges for the promenades. He was always one of those who haunted the prefect when the hour for departure drew near. He was impatient to know where they were to go: 'Where are we going?... Shall you take us to the Grand Palais? (The Automobile and Aviation Exhibition).... Wouldn't you be a brick!...' When they arrived, he was not one of those many curious people who circulate aimlessly around the stands with their hands in their pockets, without reaping anything but fatigue, like a cyclist on a circular track. His plans were all made in advance, and he knew where the stand was which he meant to visit. He went directly there, where his ardor and his free and easy behavior drew upon him the admonitions of the proprietor. But nothing stopped him, and he continued to touch everything, furnishing explanations to his companions. When he returned to the college his pockets bulged with prospectuses, catalogues, and selected brochures, which he carefully added to the heterogeneous contents of his desk."[11] [Footnote 11: Unpublished notes by Abbe Chesnais.]
