This building is devoted to the display of every known vehical used for transportation purposes, and for every known means of power utilized to propel them. Their classification covers a wide range: from a baby carriage to a 100-ton locomotive, and from a cash carrier or a carrier pigeon, to a balloon. Its position in the grounds is one of the group forming the northern quadrangle farthest from the lake front but facing the lagoon, and with an extensive view of the wooded island. It is more simple in general design than many buildings of its size, but withal bears many beautiful architectural details, and is rendered especially conspicuous by its "Golden Door" as the large arched main entrance is termed. This feature of the building is an immense single arch, most elaborately ornamented with carving, bas-reliefs and mural paintings, all treated with gold leaf, forming a rich and beautiful effect. Numerous minor entrances are from time to time pierced through the walls, which, with the continuous line of window arches and the glory of the "Golden Door," relieve the long facades from any, tincture of severity.

   The cupola, placed exactly in the center of the Transportation Building, is one of the finest view points obtainable. It is reached by eight elevators and is one hundred and sixty-five feet high. The interior suggests cathedral proportions, with its long nave and aisles. The roof is formed in three divisions, the center one much higher than the others, and its walls have the same continuous line of arched windows which admit floods of light. The abundant elevator facilities permit visitors to reach, without fatigue, all parts of the building, by way of galleries at various stages of height.

   In addition to the main building an enormous annex is added, covering about nine acres, wherein the heavier and more bulky exhibits will be displayed. This is but one story in height, and will contain railroad tracks at intervals of sixteen feet throughout, upon which are shown the modus operandi, of railroad equipment the making up of trains, the trial of patent devices and what not. An impossing array of locomotives will appear on dress parade daily, placed facing each other down the long central avenue. The earliest locomotives used in America and the first passenger cars hauled, form an interesting study of comparison when placed beside the modern mogul or express engine and the latest pattern vestibuled train.
