At the north end of the Agriculture Palace, was the Great Floral Clock, which operated from 8am to 8pm .
Christian Bernard Mundt, was the Floral designer commissioned by Cornelli Seed Company, while Paul J. Ostrowski, a Polish youth from Milwaukee, was the engineer of the 112 foot wide floral clock- the largest clock in the world. The mechanism was run by compressed air, while motive power originated from the Exposition power house.
The minute hand alone weighed more than a ton (2,700 pounds), and was 75 feet long. The massive hand moved five feet per minute.
The smaller The hour hand was 50 feet long.
Each number, composed of flowers was fifteen feet tall.
At the upper edge of the dial, stood a 5,000 pound bell was struck on the hour and half hour.
The clock would then have 13,000 flowering plants covering its face. At night, it was said to have been illuminated by a thousand lights.
A large bronze gear mechanism turned the hands by a steel shaft 4 inches in diameter, which ran underground to a pavilion outside of the dial circuit. The master pneumatic clock was a smaller timepiece that controlled the gigantic floral timepiece, it was created by the Johnson Service Company of Milwaukee Wisconsin in 1903.
