In the light of this prediction it is interesting to note that in 1900 the vessels mooring or weighing anchor there numbered 17,553, and brought and carried away cargoes aggregating 14,236,190 tons. Nevertheless, for some years, because of the quagmire condition of streets and the frequent inundations from lake and river, Chicago was termed derisively the "amphibious town." By filling in the land, the city long since literally lifted itself out of the mud, the level of streets to-day being eight feet above the original marsh. But even before the transformation of the town into a city, it was plain that the founders had come to build it into a centre of trade and population. Encouraging progress was being made on the Illinois and Michigan Canal, the population of the town was increasing, neighboring prairies were being tilled, and the water carriers who drove their carts into the lake, filled their barrels, and then distributed water by the bucketful, were giving way to the Hydraulic Company. A new era was at hand, and Chicago on the 4th of March, 1837, became an organized municipality. The first census, taken in July, 1837, showed a population in the city of 1800 men, 845 women, and 1344 children. With a colored population of 77, the grand total of inhabitants in this its first year's existence as a city was 4066. To-day its population is nearing the two-million mark. O.D. Wetherell, ex-city Comptroller, recalls a letter, written at an early date by a citizen, in which the prediction was made that some day Chicago would become a city of 10,000 people! At the time, that prophecy seemed to be more wildly optimistic than would a prediction now that the city might ultimately harbor the amazing total of ten million persons. The early promoters of Chicago were sanguine of a great future, but none dreamed of the amazing destiny in store. At a political gathering in 1838, addressed by Stephen A. Douglas and John T. Stuart, his competing candidate for Congress, a local orator, warmed by the enthusiasm of the occasion, uttered what was derisively referred to the next day as "flamboyant prophecy." "The child is already born," he exclaimed, "who shall live to see Chicago a city of 50,000 souls." "Town lots, town lots!" shouted the audience in amiable sarcasm, not wishing the visiting statesman to depart with the suspicion that dreams of real-estate speculation had destroyed the sanity of the whole community. For three years the town had been the centre of a great land craze, one of the first real-estate booms that have played so important a part in the location and development of Western cities. Dr. Horace Chase, writing in 1883 from Milwaukee, says:
