At 66-72 Adams Street, is 80 feet wide, 100 feet deep, and 60 feet high, with 3 stories and basement. It is a brownstone front, and its upper stories contain 4 halls for the accommodation of councils or lodges of the mutual insurance association known as the National Union. These rooms are patriotically called Washington, Jefferson, Franklin, and Lincoln halls. It was the method of this society, at first, to unite certain professions in separate councils. But the Press Council, as an instance, beginning with many journalists and printers, has added hundreds of the leading railway men to its membership, greatly to the advantage of all conerned. Erected in 1888.

At 80-84 Adams Street, is 50 feet wide, 105 feet deep, and 140 feet high, with 8 stories and basement. The structure is of the steel pattern, with heavy brick walls and terra cotta and tile. There are 2 stores, 140 offices, and 2 passenger elevators. The occupants are insurance companies, real-estate dealers, and manufacturers' agents. Erected in 1892, at a cost of $150,000.

Fronts 50 feet on Adams and 75 feet on Dearborn Street, at the southeast corner. This 14-story structure, on a lot so small, at a corner so conspicuous, produces a monumental effect. The brick used in this edifice were the first in the Western world to imitate in shape and color the brick used by the ancient Romans in the Eternal City. A tower with cupola, and ornate treatment at the roof, enhance the architectural effect. The history of this peculiar edifice is further given in our chapter on "Notable High Buildings." There are 168 offices and 3 passenger elevators, averaging 900 trips a day. The occupants are financial and coal companies, investors, and professional men. The Owings Building was erected in 1888, at a cost of $475,000, and like the Monadnock, Manhattan, Unity, and others is a genuine Chicago sky-scraper.

Fronts 100 feet on Dearborn and 180 feet on Quincy Street, at the northeast corner, and is 100 feet high, with 9 stories and basement. It is built of stone, brick, and terra cotta. There are 8 stores, 400 offices, and 3 elevators. The occupants are coal dealers, capitalists, brokers, attorneys, scientific experts, manufacturers' agents, and professional men. Erected in 1887.

Occupies a square bounded by Adams, Clark, Jackson, and Dearborn streets, but the building, standing in the center of this plot of ground, has a width on Adams and Jackson of only 212.5 feet, and a length on Clark and Dearborn of but 305.2 feet. After the destruction of the old Post Office, at the northwest corner of Monroe and Dearborn, there was a strenuous attempt to buy the whole of that square for the Federal Government, but the property was considered too high-priced. Some further history of this institution in Chicago is given in our chapter on "Notable High Buildings." Its weight was too great for the soil, and there has always been an uneven settlement, destructive in character, and at times dangerous to the occupants. To hold it together, heavy rods have been run through the upper walls. The material entering into the construction of this fabric is of the best--Buena Vista sandstone, steel, cement, terra cotta, brick, and marble. The heavy stone walls rise to a height, with their roof, of 102 feet, and there are 4 stories and basement. On the three upper floors are 65 rooms, occupied by 8 divisions with 20 different departments of the Gevernment service. On the main floor, surrounded by a great lobby, is the Post Office. In the building are 3,500 employes, who use 1 freight, 10 mail, and 4 passenger elevators. Into this house, which never closes, it is estimated that 50,000 persons go every day.

At 110-114 Jackson Street, is the property of the most popular and influential social organization in the city. Its membership is nearly 2,000, and it has exceeded the political bounds and restrictions under which it was founded. Nominally a Republican society, it has become, under the liberal influence of the World's Fair, a potent factor in the every-day life of the city. In its ranks are nearly all the ambitious young successful tradesmen of the city, and professional men have not been slow to ally themselves with a body so active and progressive. The striking and luxurious home of the club fronts 100 feet on Jackson Street and is 60 feet deep, with 5 stories and basement. There are 74 rooms above the street. The walls are 100 feet high with roof, and the material is granite and brick. There are 125 employes. About 400 people enter the club daily. Erected in 1887. Cost, $500,000.

Covers the very long and narrow block bounded by Jackson, Dearborn, and Van Buren streets and Custom House Place (once Fourth Avenue). The front on Dearborn Street is 420 feet; the depth is but 70 feet. The walls, which are among the very heaviest brick constructions in the city, rise to a height of 180 feet, with 16 stories, and exhibit fine specimens of constructive skill. All the strength and security of a steel and tile interior are added to make the Monadnock permanent and popular. In this astonishing edifice there are no less than 1,600 offices and 18 passenger elevators. Great corporations, banks, and professional men are to be found here--among them the Santa Fe, the Michigan Central, and the Chicago & Alton railroads, and the American Exchange National and the Globe Savings banks. Electricians, attorneys, agents, capitalists, and commission merchants also gather here. Erected in 1891-93, at a cost of $2,500,000. (See "Notable High Buildings.")

At Dearborn, Jackson, and Quincy streets, on the northeast corner of Jackson and Dearborn, is a high steel structure that preserves many canons of old-style proportions. Like the Rookery, the Siegel-Cooper, and the First National the Great Northern is impressive on the lines of grace and beauty. The dimensions of this colossal structure are as follows: Front on Dearborn, 165 feet; depth on Jackson and Quincy, 100 feet; height 185 feet; 16 stories and white marble basement. In this hotel are 500 rooms, 8 dining-rooms, cafe, and 6 elevators. A prize was publicly offered for a name, and given to the suggestor of the title "The Chicago." This title was abandoned for the present one. The plan of entertainment is strictly European. The appointments and modern character of this hotel give it a conspicuous place among the sights and conveniences of Chicago. The proprietors are Hulbert & Eden, highly experienced and well-known landlords. Erected in 1891, at a cost of $1,150,000.

Fronts 40 feet on State and 147 feet on Jackson Street, at the southeast corner. It is an imposing 6-story building of the style of 1872, with 2 passenger elevators, and 40 offices on the upper floors. The three lower stories are occupied by Spaulding & Co., extensive manufacturers of silverware.

At 265-273 Dearborn Street, extends through to Plymouth Place (once Third Avenue) on the east, and is 100 feet wide, 80 feet deep, and 75 feet high, with 6 stories and basement. There are 60 offices and 1 elevator. The walls are of stone and iron. Publishers, printers, agents, and jobbers occupy the premises. Erected in 1875, and owned by the estate that built the Old Colony, opposite.
