From the north side of Grant Park and extending south to Garfield boulevard near Washington Park is Michigan Boulevard. This historic drive, part of which was once an Indian trail, is a main artery of automobile travel from the lake front hotel districts to the south parks.

The party then took a surface car to Jackson Park, which was a short distance. It was the site of the world’s Columbian Exposition.

“The Field Museum of Natural History was the Fine Arts Building in the Exposition of 1893,” said Mr. Ludlow. “Let’s visit that part first.”

This museum was established soon after the close of the world’s Columbian Exposition, and occupies one of the largest and most beautiful buildings in the whole exposition group covering two acres. The building is classic Greek in style, constructed with brick and steel, covered with ornamental stucco, in imitation of marble.

Marshall Field, whose name the institution perpetuates, was the person who made the building possible by his generosity. He gave about one and a half million dollars. Then at his death in 1906, he left the institution eight million dollars, one-half for endowment, and the other half for a magnificent permanent building, worthy of the unrivaled scientific collections which it contains.

The nucleus of the material now on view was gathered by gift and purchase from exhibitions at the world’s Columbian Exposition.

From here they walked to the Wooded Island, an interesting feature of which is the Cahokia Court House, reputed to be the oldest public building in the whole Mississippi valley.

It was built, it is said, about the year 1716, at Cahokia, Illinois, and has served in various public capacities. At different periods it was employed for both civil and military purposes, and is recognized as the oldest county seat building (Saint Clair County, Illinois) in the original Northwest Territory.

The building is constructed of squared walnut logs, set on end in the early French manner of stockade construction, the logs being held together with wooden pins. Three flags, French, English and American, float from the flagstaff of the Old Cahokia Court House, daily.

Within the building are a number of photographs of the original documents which pertain to its interesting history.
