Part 1 of Wonders of World Engineering was published on Tuesday 2nd March 1937, price 7d.
It was a bumper issue of 36 pages, all other issues being 32 pages. The issue included a superb folding colour plate showing a cutaway drawing of an Empire Flying Boat which accompanied an article with the same title. There was also a central photogravure supplement illustrating the article on Harnessing Niagara. All these are illustrated below.
The cover shows the Oakland Bay suspension bridge under construction. At this time it was the world’s longest bridge. Its construction is described in the article on San Francisco's Great Bridges.
A ferry service that carried 45,000,000 people across San Francisco Bay every year has been superseded by two of the biggest bridges in the world. Built at a cost of nearly £24,000,000, they are among the most spectacular bridge-building achievements ever undertaken. This chapter is the first article in the series on Linking the World’s Highways. The article covers the construction of the Oakland Bay and Golden Gate bridges.
A GIANT OF THE AIR, the new Empire flying boatCanopus is one of the twenty-eight craft designed for service on Empire air routes. The flying boat has a length of 88 feet from nose to tail and a wing span of 114 feet. She has a maximum speed of 200 miles an hour and a ceiling of 20,000 feet. Navigation and wireless transmission and reception are carried out on the upper deck, where the mail compartments are also situated. The lower deck is mainly occupied by passenger accommodation. The Canopus is driven by four Bristol “Pegasus” engines, each developing 920 horse-power. Fuel tanks with a standard capacity of 600 gallons are embodied in the wings.
THE CONCRETE-LINED CANAL through which water is diverted from Chippawa to Queenston. The section illustrated was cut through solid rock with an over-layer of earth, and the bottom of the canal is, in places, 143 feet below ground level. More than four million cubic yards of rock were blasted and thirty million cubic yards of earth were excavated during the building of this canal.

THE POWER-HOUSE AT QUEENSTON, on the lower reaches of Niagara River, stands at the foot of a cliff 300 feet high. A waterway nearly 13 miles long brings water from Chippawa, above the Canadian Falls. The great screenhouse at the top of the cliffs at Queenston contains the entrances to ten penstocks or pipes through which the water passes down to the hydraulic turbines in the generating station. The Queenston-Chippawa scheme is the most modern and the most powerful of the hydro-electric undertakings at Niagara.

NIAGARA'S SCENIC BEAUTY has not been marred by the huge generating stations that have been built near the Falls. Opposite Goat Island, which separates the American and Canadian Falls, is the Ontario Power Company's Station, built at the base of the cliffs. Above the Canadian Falls, near the centre of the illustration, is the Toronto Power Company's station, which overlooks the upper rapids. The road bridge in the foreground connects Canada (right) with the United States of America.

IN THE GREAT GENERATING STATION at Queenston - built for the co-operating municipalities of Ontario by the Hydro-Electric Power Commission - ten giant turbines develop a total output of more than 550,000 horse-power. Only the upper frames of the units are visible, the alternators and turbines being encased in concrete below the floor level. The power generated in this station, transformed up to 110,000 volts, is transmitted over distances of more than 250 miles.
A group of twelve towering masts at Rugby is the outward sign of a modern engineering marvel and a vast radio organization that links Great Britain with ships on the high seas and with every corner of the world. This is the story of the General Post Office’s Radio Station at Rugby.
Crude oil is transported directly from its source to the consumer through 1,150 miles of pipe line, the laying of which across the desert involved an expense of £10,000,000 and the employment of 10,000 men. This chapter describes the construction of the pipe line from Kirkuk in Northern Iraq to the ports of Haifa and Tripoli on the Mediterranean coast. The work was undertaken by engineers of the Iraq Petroleum Company.
