139-D The caption of this post card says The unique Aerial Lift Bridge and Ship Canal Entrance to Duluth-Superior Harbor is an outstanding attraction of this popular summer vacation city. Total bridge load lifted is 900 tons. Only 55 seconds are required to lift the span 135 feet. The Harbor is second only to that of New York City in shipping tonnage and through it passes about 60 per cent of America's iron ore production, from the great iron ore ranges just north of Duluth. Another fact, not included in the caption is that John H. Darling (1847-1942), U.S. Engineer for Duluth-Superior Harbor, oversaw replacement of the original wooden canal piers with concrete piers in 1897. The piers have been maintained and repaired with a major remodeling/rehabilitation in 1985-1986.

The Chicago Shipbuilding Company of Chicago, a subsidiary of the American Shipbuilding Company, built the steamer William E. Cory for the Pittsburgh Steamship Company in 1904. The vessel dimensions are 569' X 56' X 31'. She sailed from Chicago on her maiden voyage August 12, 1905 bound for Duluth to load iron ore. The aerial bridge was new. Bids were opened March 25, 1901, but only one was received. The Duluth Canal Bridge Company was awarded the contract but abandoned the work. In February 1904, the Modern Steel Structural Company of Waukesha, Wisconsin was issued a contract. Work began July 20, 1904. On February 23, 1905, with local dignitaries at hand, the bridge was first operated. Regular service began the next day according to newspaper accounts. The city engineer's report for 1905 stated that the bridge was "completed and commenced operation on May 5, 1905, and a few problems were corrected in running the bridge over the next few days." The Aerial bridge was completed in February 1905. The aerial bridge transporter or gondola or transfer car roadway was 17 feet by 50 feet with sidewalks seven feet by 50 feet, the cabins were 30 feet long. The U.S. Army Corps of Engineers office building with flag above it was built in 1906. Also visible in the image are the National Biscuit Company 517 Lake Avenue South, Blanchet Hotel 520 Lake Avenue South, and Wieland Flats 502-512 St. Croix Avenue

Whaleback is an unusual ship design with steel hulls (body of the vessel) and rounded decks (boat, hurricane, main -which is the lowest full-length deck in a ship's hull, and spar are all decks at different levels) which was introduced by the inventor Captain Alexander McDougall of Duluth in 1888. It was a very stable vessel. American Steel Barge Company, a New York corporation engaged in shipbuilding and transportation on the Great Lakes as well as on the Atlantic and Pacific coasts, purchased all of the patents for McDougalls whaleback vessels for $25,000. The only remaining whaleback is the Meteor, which is now a museum at Barker's Island in Superior, Wisconsin.

This photograph may have been shot from Seventh Street and about Lake Avenue. The bright narrow strip in the lower middle of the image is Lake Avenue leading to the Aerial Bridge. The rectangle and three dots parallel to the piers of the canal are the remnants of the Whitney rock crushing enterprise. The Whitney Brothers, of Superior, Wisconsin, had a sand and gravel processing business that was functioning in 1919. The concrete form that is still in the water was the dredging/crushing building. A tunnel ran from the building to the Point. There was a conveyor belt and railroad spur adjacent to the concrete building. Sand from the Apostle Islands and gravel from Grand Marais were carried to Duluth on a small vessel named Limit. The business also used a tug the William A. Whitney. The Limit was secured to the concrete building and the load of sand or gravel was unloaded into the steel hopper using a jaw-like clam shell, steam powered device. The belt conveyed the materials to shore and it dropped into a tunnel where trucks were ready. On Federal lake charts it is referred to as cribs. Telephone lines are in this photograph. In 1880, the first telephones were installed in Duluth by Walter Van Brunt for C. H. Graves and Company. In 1881, the Duluth Telephone Company was incorporated with $10,000 capital. In 1882, the first telephone directory was issued for 30 subscribers. In 1898, long distance lines between Duluth, Cloquet and Carlton were strung. In 1899, Duluth had 794 telephones. In 1900, the Zenith telephone Company (independent) started operations in competition with Duluth Telephone Company. The tower is the Central High School clock tower. The 1892 school has been the Central Administration Building for ISD 709 since the late 1970s.

Hillside housing stock built with a rock outcrop in the backyard; A Master Bread billboard is at the top of the image. The Zinsmaster family opened a bakery called Zinsmaster Hol-Ry Company in Duluth in 1931. Master Bread was one of their brands. The structure that looks like it is framed by the Aerial Lift Bridge is the Huron Portland Cement silo that later became LaFarge Cement. It still stands on the Duluth waterfront. The white trimmed brick structure at the top right is 1515 West Superior Street, the Duluth Gospel Tabernacle building. The building to the right but further east on Superior Street with the arched window is a Minnesota Power station and garage at about Fourteenth Avenue West and Superior Street.

Ore boat leaving Duluth. Detroit Publishing Co. was a prolific post card publisher, especially in the U.S. Their cards were published from 1898 to 1933. Using a color process called Phostint, their cards were considered to be very artistic. The hobby of collecting post cards is called deltiology. The first post card was issued by the Austrian government, America's first postcards came out in 1873. Picture postcards were introduced later. The golden age of postcards was supposed to date from 1907 through the first World War.

In 1893, James J. Hill's Northern Steamship Company built 385-foot ocean style passenger steamers. In 1911, the peak year, 80,000 passengers traveled to Lake Superior. After 1920, the number of passenger cruise ships diminished with the advent of "motor-cars." Very few cruise ships were still in service after World War II. The Canadian steel steamer Huronic was constructed in Collingwood, Ontario, in 1902. She ran on the Northern Navigation Division of the Canadian Steamship Company, on cruise trips from Detroit to Duluth. In 1940, the Huronic was dismantled and made into a package freighter.

Most photographs of downtown Duluth will also capture the Aerial Bridge, and so it is with this image of Superior Street at Fifth Avenue West. The Spalding hotel was completed in June 1889. It was razed in the summer of 1963 along with many other buildings in the Gateway Renewal Project. The total cost of razing Gateway buildings was $258,000, including demolition of the Spalding hotel at the cost of $43,500.

Marshall-Wells Hardware merchandise is loaded and ready for delivery to various railroad lines for transport. The first horse-drawn sleigh will take the orders packed into it to the Chicago, St. Paul, Minneapolis and Omaha depot. The truck behind the sleigh is destined for the Soo Line depot. The next in line will be shipped on the Great Northern railway and the one after that will go to the Northern Pacific. The Union Depot served seven railroads including the GN and NP. It still stands as the St. Louis County Heritage and Arts Center. All of the other depots are gone. The Marshall-Wells Company started in 1886 as Chapin and Wells Company a wholesale hardware business. Albert Morley Marshall, son of Seth, bought controlling interest in 1893 and changed the name to Marshall-Wells Company. The company grew to include 14 wholesale offices throughout the northwestern U.S. and Canada. In 1955 Ambrook Industries Inc. of New York bought controlling interest. Kelley-How-Thomson and Marshall-Wells merged January 1, 1958. Kelley-How-Thomson had been a subsidiary of Marshall-Wells since 1955 when Ambrook bought Marshall-Wells and reorganized. The Coast-to-Coast Stores bought the Duluth division of Marshall-Wells-Kelley-How-Thomson Company in 1958, which ended the Duluth firm's operation. Also in the image are the People's Hotel 246 Lake Avenue South, and the Lyceum Theater billboard.

The original building was built in 1891 at the foot of Seventh Avenue West and the bay front. This, the second facility, was built in 1906 at 1000 Minnesota Avenue on the harbor side. This was a social center of Duluth but you did have to buy a membership. It had nearly 200 rowboats, canoes, and a flotilla of sailboats. Duluth rowers won 20 national championships between 1911 and 1923, as well as hosting the national races in 1916. The club dissolved in 1926 due to flagging interest and debt.

Passenger steamer North American of the Georgian Bay Line is steaming out of Duluth harbor leaving Duluth. There were many passenger ships and companies used similar names. This vessel had a partner named the South American; both were built in 1913. The Great Lakes is one of the oldest, yet one of the newest cruise destinations. Cruises were being taken as early as 1842, yet the industry had almost disappeared 100 years later. Railroads bought and built steamship lines to compliment railroad services. Some activity continued into the 1960s, but following the departure of the South American in 1966, cruising effectively ceased for thirty years. Houses on Minnesota Point are at the left. The Aerial Bridge gondola or basket transporter is visible behind the stern. These lamp posts on the piers remained until about 1955. This is a print made from a broken glass plate negative: the bottom right corner is missing (black). The photographer's negative number is cut off, only the beginning of his name shows "McK."

The information on this post card says Crowd leaving bridge; The Aerial Bridge; Miniature Train, White City. Joyland White City was the name of the amusement park at the end of Minnesota Point at Oatka Park. It was named White City based upon the buildings constructed at the recently experienced World's Fair where buildings were constructed using "white" building materials. There were rides and a pavilion for performances, dances and music. White City was short lived, about 1905-1911. The pavilion remained and the location reverted to the prior name of Oatka Park. The small train was moved to the Duluth zoo when the last features of the amusement park were dismantled in the 1950s. This post card was mailed in July 1907.

This view shows the waterfront when it was warehouses and wharves, docks, railroad freight sheds and slips. This view is probably from Skyline boulevard which, at this time, would have been called Rogers' Boulevard. William Rogers was the first parks department commissioner. In December 1959 the Duluth City Council and Mayor E. Clifford Bork changed the name of Rogers parkway and Skyline Boulevard to Skyline Parkway.
