leave to England, “where he arrived in February 1854. He next 
obtained the post of engineering superintendent of the Arthington 
Extension Waterworks under Mr Hawkesley, with whom he re- 
mained till the completion of the work, when he received a flatter- 
ing letter from Mr Alderman Hepper, chairman of the Leeds Water 
Works Committee, expressing the great satisfaction of that body 
with the manner in which he had conducted the works. Returning 
to London, Mr Rumble experienced some difficulty in finding 
employment to his taste, and was, for short periods, draughtsman 
in the offices of Messrs Conybeare and Brikinshaw, the London and 
South-Western Railway Company, the Admiralty, &c., till in 1857 
he was appointed engineer to the Atlas Steel Works, then entirely 
in the hands of Mr (now Sir) John Brown, in which capacity he was 
entrusted with the conduct of many transactions requiring much 
tact and diplomacy. In 1858 Mr Rumble was elected Fellow of 
the Society of Engineers' in 1860 a member of the Institute of 
Mechanical Engineers ; in 1861 a member of the Institute of Naval 
Architects ; and in 1866 a Fellow of the Royal Microscopical Society, 
in the proceedings of which body he was always deeply interested. 
During these years Mr Rumble had opened an office in West- 
minster, and was practising as a civil and mechanical engineer, and 
was fortunate enough to secure much good work. In 1869 he paid 
a second visit to the United States, and spent six months visiting 
many engineering shops and acquiring a thorough knowledge of the 
recent mechanical improvements. Shortly after his return to Eng- 
land, Mr Rumble had the honour of two interviews with his late 
Majesty the Emperor Napoleon, who was pleased to express his satis- 
faction with the plans, drawings, &c., submitted for his approval. 
On New Year’s Day, 1872, Mr Rumble was again in New York, and 
visited the various Safe Deposit Companies in that and other cities, 
with the view of obtaining information for the National Safe Deposit 
Company, then about to be formed in London. He visited Phila- 
delphia, Boston, Halifax, &c., and the ruins of Chicago, then scarcely 
cold after the great fire, and examined the vaults and safes remain- 
ing intact. He returned to London on the 28th January, and was 
for the rest of the year employed in designing the safes, strong-rooms, 
buildings, and other arrangements of the National Safe Deposit 
Company, which were afterwards carried out under his superintend-
