cloud-burst may move a town. Great visitations, like the Chicago fire or the San Francisco earthquake, reveal these social processes in larger and more legible scale. Take as a single instance the latter city. Its quick recovery has been called one of the wonders of the age. In the very midst of surrounding desolation and business extinction, the Californian city projected a Panama-Pacific exposition, and its citizens proceeded to arrange for one of the greatest of all world fairs. On the other hand, the social changes which succeed relatively small disturbances are often such as to elude an estimate. The reason has been well suggested that “big crises bring changes about most easily because they affect all individuals alike at the same time.” In other words a more general fluidity is accomplished. We see, therefore, a second principle begin to emerge. Not only is fluidity fundamental to social change, but the degree of fluidity seems to vary directly as the shock and extent of the catastrophe.

There yet remains to notice the bearing of catastrophe upon social progress. The following words are quotable in this connection:

It is quite certain that the degree of progress of a people has a certain relation to the number of disturbances encountered, and the most progressive have had a more vicissitudinous life. Our proverb “Necessity is the mother of invention” is the formulation in folk-thought of this principle of social change.[15]

We cannot, however, remain long content with this suggestion as to the principle concerned—namely, that progress is a natural and an assured result of change. The point is that catastrophe always means social change. There is not always progress. It is well to guard against confusion here. Change means any qualitative variation, whereas progress means “amelioration, perfectionment.” The latter will be seen to depend on other things—the nature of the shock, the models presented, the community culture and morale, the stimulus of leaders and lookers-on. The single case of Galveston, Texas,[16] is sufficient to disprove the too optimistic hypothesis that the effects of catastrophies are uniform. Here a city lost heart by reason of the overwhelming flood, and in spite of superior commercial advantages was outgrown by a rival fifty miles away. At the same time the case of Dayton, Ohio, should be borne in mind. Here also was a flood-stricken city and she became “the Gem City of the West.” The principle[17] thus appears to be that progress in catastrophe is a resultant of specific conditioning factors, some of which are subject to social control.

It is indeed this very thing which makes possible the hope of eventual social control over disaster-stricken cities, and the transmutation of seeming evil into tremendous good. And this is in addition to the many practical social lessons which we have already been intelligent enough to preserve, such as those of better city-planning, and a more efficient charity organization.

How much of man's advancement has been directly or indirectly due to disaster?[18] The question asks itself and it is a question as yet without an answer. When the answer is at last written, will there not be many surprises? Pitt-Rivers tells us that “the idea of a large boat might have been suggested in the time of floods when houses floated down the rivers before the eyes of men.”[19] A terrible storm at sea gave America its first rice.[20] City-planning may be said to have taken its rise in America as a result of the Chicago fire, and the rôle of catastrophe in the progress of social legislation is a study in itself. The impetus thus received is immeasurable. Historically, labor-legislation took its rise with the coming of an infectious fever in the cotton-mills of Manchester in 1784. After the Cherry mine disaster legislation ensued at once. Again it was the Triangle fire which led to the appropriation of funds for a factory investigation commission in the State of New York. The sinking of the Titanic has greatly reduced the hazards of the sea.

It may easily prove true that the prophets of golden days to come who invariably arise on the day of disaster, are not entirely without ground for the faith which is in them; and that catastrophies are frequently only re-agents of further progress. But this is merely introductory. Thought becomes scientific only when its conclusions are checked up and under-written by observation or experiment. Prior to such procedure it must still remain opinion or belief.

The whole subject is, it must be repeated, a virgin field in sociology. Knowledge will grow scientific only after the most faithful examination of many catastrophies. But it must be realized that the data of the greatest value is left ofttimes unrecorded, and fades rapidly from the social memory. Investigation is needed immediately after the event. It is, therefore, of the utmost importance that sociological studies of Chicago, Galveston, Baltimore, San Francisco, and other disaster cities should be initiated at once.[21]

Of such a series—if the work can be done—this little volume on Halifax is offered as a beginning. It is hoped that the many inadequacies of treatment will receive the generous allowances permitted a pioneer.

CHAPTER I
Catastrophe and Social Disintegration

The City of Halifax—Terrific nature of the explosion—Destruction of life and property—The subsequent fire and storms—Annihilation of homes—Arresting of business—Disintegration of the social order.

Halifax is the ocean terminal of the Dominion of Canada on her Atlantic seaboard. It is situated at the head of Chebucto Bay, a deep inlet on the southeastern shoreline of Nova Scotia. It is endowed by nature with a magnificent harbor, which as a matter of fact is one of the three finest in the world. In it a thousand vessels might safely ride at anchor. The possession of this harbor, together with ample defences, and a fortunate situation with regard to northern Europe established the Garrison City, early in the year 1914 as the natural war-base of the Dominion. Its tonnage leaped by millions, and it soon became the third shipping port in the entire British Empire. Hither the transports came, and the giant freighters to join their convoy. Cruisers and men-of-war put in to use its great dry-dock, or
