JOHN YULE.

The death is announced of Mr. John Yule, of the Hutchestown Engine

Works, Rutherglen, N. B., at the age of 66. During early life, Mr.

Yule went the round of the best engineers' shops in Scotland and

England, and became one of the recognized leaders in engineering

progress. His inventiveness took various directions, amongst other

fruits being an improved rotary engine, a compensating governor for

the steam engine, and a screw tap, drill, and mandrel. For the latter

he was awarded the silver medal of the Scottish Society of Arts. For

some years Mr. Yule acted as the manager of the boiler department of

Messrs. Robert Napier & Son's establishment, but eventually resumed

business at the Hutchestown Works, and devoted attention amongst

other matters to the improvement of swing bridges and steam cranes and

hammers. In the former line two of his most important works are the

plate girder bridge over the entrance to one of the docks at Port

Glasgow, for the Caledonian Railway, erected from plans by Messrs.

Bell and Miller, C.E., Glasgow; and a lattice girder bridge over the

entrance to Kingston Dock, Glasgow Harbor. Owing to the angle at which

this last bridge crosses the dock, great difficulties were experienced

in working out the mechanical details so as to admit of easy motion.

These were skillfully overcome, and the bridge was, as finally

erected, a monument of his design as well as workmanship. The

Blackhill incline on the Monkland Canal, constructed nearly a quarter

of a century ago, is a sample of Mr. Yule's mechanical powers. Of late

years he was largely engaged as a professional valuator.
