THE CEARA HARBOR WORKS.

The works illustrated by the engravings are now being constructed

under a concession from the imperial government of Brazil. The

province of Ceara has an area of about 50,000 square miles, and is one

of the richest in Brazil. Its produce comprises sugar, coffee, cocoa,

cotton, tobacco, spices, fruit, cabinet and dye woods, India rubber,

etc. Its population at the last census, taken in 1877, amounted to

952,624 inhabitants, that of the capital, the city and port of Ceara,

being about 40,000. Although Ceara is the principal seaport at which

lines of English, French, American, Brazilian, and other steamers

regularly call, prior to the commencement of the harbor improvements

it was almost an open roadstead, passengers and goods having to be

conveyed by lighters and boats between vessels and the shore. The

official statistics of the trade and shipping of the port show that an

income of £35,750 per annum will be collected by the Ceara harbor

corporation from the dues which they are authorized by their

concession to charge on all imports and exports and on the vessels

using the port and from the rent of the bonded warehouses.

The drawings given here show the nature of the works, which are of a

simple character. The depth of water along the principal quay, which

is being constructed of solid concrete, and is connected with the

shore by an iron and steel viaduct over 750 ft. in length--which is

already completed--will be 19 ft. at low water and 25 ft. at high.

This quay and breakwater is shown in perspective, in plan, and in

section, and is of a very heavy section, as will be gathered by the

scale given immediately below it. Meanwhile the landing of cargo is

temporarily carried on at the end of the viaduct, which at high tide

has a depth of about 20 ft. of water. The custom house and bonded

warehouses are being built of the fine granite obtained at the Monguba

quarries, which adjoin the Baturite railway, about sixteen miles from

the port. A new incline has also been constructed from the rail way

down to the port. The line has been laid along the viaduct, and will

be extended over the quays as soon as they are completed. The

concrete, of which a large quantity is being used, is mixed by Carey &

Latham's patent mixers, and the contractors have supplied the very

large and complete plant for carrying out the operations.

The engineer to the corporation is Mr. R.E. Wilson, M. Inst. C.E.,

Westminster, and his resident at Ceara is Mr. R.T.H. Saunders, M.

Inst. C.E. The contractors for the work are Messrs. Punchard,

McTaggart & Co., their representative at Ceara being Mr. George

Wilson, M. Inst. C.E._--The Engineer._
