The revenues of the corporation, which are very considerable, are derived from tolls paid by the shipping deriving benefit from the lights, beacons, and buoys, and from the ballast supplied. Also from lands, stock, &c. held by the corporation, partly by purchase, partly from legacies, &c. and donations of private individuals. The whole of these revenues are employed in necessary expenses, such as constructing and maintaining their lighthouses, and lights, beacons, and buoys, and the buildings and vessels belonging to the corporation, in the salaries of the officers of their different establishments, and in relieving decayed seamen and ballastmen and their widows. Many almshouses have been erected and are maintained from the same funds. The present house of the corporation is on Tower Hill. It was built by Wyatt in 1793. It is of Portland stone, with a rustic basement, over which is one story adorned with Ionic columns and pilasters. The Trinity House was formerly in Water Lane, where it was twice destroyed by fire. The members of the corporation are chosen from among the highest ranks: of the thirty-one elder brethren, eleven are noblemen and heads of the government departments, admirals, &c. These are styled honorary members, and have no pecuniary advantage from their connection with the institution. The present master is the Duke of Wellington. Mr. Pitt filled that office for seventeen years, and William IV. was master at the time of his accession to the throne. Different committees are appointed for attending to the various duties of the corporation. The deputy master and elder brethren are from time to time employed in making voyages of inspection of their lighthouses and lights, beacons and buoys, and in making surveys &c. on the coast, and reports on maritime matters. The salary of the deputy master is six hundred pounds per annum, and of the elder brethren three hundred pounds each per annum. The duties of the corporation also extend to the examination of such boys of Christ’s Hospital as shall be willing to become seamen, and to apprentice them to commanders of ships. Also, the appointment of all pilots into and out of the Thames, prohibiting under penalties all other persons from exercising the office; the punishment of seamen deserting, &c. All masters of the Navy, as well as the pilots, also undergo examination before this corporation.
