ROBERT LYON MACKENZIE Ross was for several years engaged on the design and construction of electric power transmission schemes for Messrs. Balfour, Beatty and Company, Ltd. He was appointed assistant engineer on the construction of overhead transmission lines and substations in the Midlands area in 1924, and was transferred in 1926 to the company's head office for the design of power lines on voltages varying from 660 to 33,000. More recently he was concerned with the design of oil-engined power stations for Africa, Palestine, and Iraq, and with the testing of the selected prime movers.

Tawse on engineering works on Viscount Cowdray's estates at Dunecht, Aberdeenshire, but left a year later to become assistant to Mr. R. Gibson, civil engineer and architect, of Dundee.
