rents and dues of various kinds for their use. Thames Tunnel.—With the view of effecting a ready communication for wagons and other carriages, and foot-passengers, between the Surrey and Middlesex sides of the river, at a point where, from the constant passage of shipping, it would be inconvenient to rear a bridge, a _tunnel_ or sub-river passage was designed by a joint-stock company. The idea of tunnelling under the river, by the way, was not a novel one. In 1802 a company was got up with a similar notion, Trevethick, the inventor of the high-pressure engine, being its engineer. It came to nought; and in 1825 Mr. (afterwards Sir) Marc Isambard Brunel began his tunnel, at a point about two miles below London Bridge, entering on the southern shore at Rotherhithe, and issuing at Wapping on the other. The water broke in in 1827, and again in 1828, when six men perished. After all the funds were exhausted, and the Government had advanced no less than £246,000 by way of loan, the work, after many delays, was opened in 1843. The total, cost was £468,000. The tunnel consisted of two archways, 1,300 feet long, the thickness of the earth being about 15 feet between the crown of the tunnel and the river’s bed. As a speculation—toll 1d.—it never paid. The descent was by a deep, dirty staircase; and only one arch was open for foot-passengers. But now that the East London Railway Company have purchased it, a wholesome change has come. Some 40 trains are now running backwards and forwards through it, from Wapping to Rotherhithe, and thence to Deptford and New Cross, and _vice versâ_. And so, at last, the once well-nigh useless scheme, which wore out Brunel’s heart, has been, some twenty-two years after his death, made of great service to that part of London. The Tower Subway.—In the neighbourhood of the Tunnel a subway has been formed, consisting of an iron tube, 7 feet in diameter, laid below the bed of the Thames. It belongs to a Limited Liability Company. It was commenced in February, 1869, and opened for tramway traffic on 12th April, 1870. Being a losing speculation, the tramway cars ceased to run on 7th December, 1870; but it was opened for foot-passengers on the 24th of that month, and it is the intention of the Company to continue it only as such. It is reached at each end by a spiral staircase of 96 steps. Its whole length is 1225 feet. A charge of ½d. is made for each person passing through this Tunnel. The Tunnel is well lighted up with gas, and the average heat by the thermometer is 65 degrees. [Picture: Albert Bridge, Chelsea]
