I joined the rush of people passing up La Salle Street to the tunnel’s pedestrian-passage entrance. Some time after leaving Monroe and Franklin Streets there was a loud explosion. I learned from the crowd making its way to the tunnel that it was the explosion of the gas works. Gas lights had gone out everywhere and the escaping gas had doubtless hastened the action of the fire in many buildings. At any rate the tunnel was dark. As we entered it in pairs with a regularity that seemed as if it were a drill, each person put his hands on the shoulders of the person in front of him and with almost a lock step, with the slogan, “Keep to the right!” “Keep to the right!” “Keep to the right!” repeated sing song by almost everyone we emerged on the North Side at Kinzie Street. Strange to say that at the same time that a double line of us was walking north through the tunnel, a single line was going south in the same order repeating the same slogan. There was no panic, no crowding, only good humor and good order. On reaching my boarding house I found Dearborn Street a mass of people and of horses and vehicles. It appeared like an aimless confusion but it was everyone looking out for himself and family without regard to others, and expecting others to do the same. It was exciting but not wildly panicky. We all realized that haste was necessary to get away somewhere out of reach of the flames which were shooting high above the blazing business district and by the light of which we were moving about inside as well as outside the houses, but frankly I saw no evidence of disregard of others’ rights in the confused moving to and fro. There were more calm people than one would expect. Our landlady had bethought herself to examine every room a few moments before I returned, she told me, and found two young men sound asleep. I saw one of those two standing on the upper landing of the outer stairs, looking wildly toward the blazing South Side. He had on a dress vest over a long linen duster. His confusion of mind was not much greater than that of most of us later when it came to a question of what we wished to save and what we could save. I found that most of the boarders were still in the house but were fast leaving with whatever they could carry. I found two, who, ignorant of the extent of the fire, still refused to believe that it would reach the North Side. At that time the air was literally full of burning embers, the wind being so strong that we saw pieces of wood two or more feet long in full blaze being driven northeastwardly.
