A party of three men embarked under Captain A. P. G. Ross, R.E., for the colony of Victoria, landed at Melbourne on the 14th October. Selected as they were with reference to their qualifications as mechanics and general intelligence, they had been appointed to oversee the skill and labour employed in the construction of works for the defence of the harbour, and the rapidly-increasing towns in its vicinity. The defence of the bay by the contemplated fortifications was reported by the Captain to be impracticable, and the party awaited for a time the decision of the provisional government on the point. Meanwhile the sappers were efficiently employed in carrying out some subordinate details connected with the Melbourne Exhibition. It was also proposed by the Harbour commission that works should at once be commenced for the extension of the wharfage on the river Yarra, to give importance and vitality to the shipping and commercial aspects of the colony. Tenders were even called for to carry out the work, but, difficult to satisfy the antagonistic views of a capricious legislature, the suggestion was indefinitely postponed. Thereupon the Captain and his three sappers returned to England, arriving at Woolwich in the summer of 1855.[118] The yellow fever, so frequently the scourge of the Bermuda islands was prevalent at St. George’s from August to November, and carried off its victims in greater numbers than in the fatal epidemics of 1819 and 1843. It commenced among the convicts in the ‘Thames’ hulk, and spread with frightful rapidity, first to the military and civil establishments, and then to the residences of the native population. The first soldier who died was a sapper, and before the sickness had ceased, no less than twenty-five men of the corps, out of a detachment of forty-seven of all ranks, became its victims. Three women and one child of the party also died. Colonel Phillpotts, the commanding royal engineer, and Lieutenant Greatorex, R.E., were among the dead, as also the wife of Lieutenant Whitmore, R.E. All the men of the detachment except three were attacked with the fever, and many suffered relapses. To relieve them as much as possible from the influence of infection, they were early removed from their quarters to an encampment on the north side of the island, near the naval tanks, and finally to Prospect Hill and Port’s Island. “Those who were able,” reports Captain White, R.E., “showed themselves to great advantage by the cheerful way in which they attended to the sick. Their exertions were above all praise.” Several opinions have been ventured relative to the exciting cause of the epidemic, but the general belief was, that from some disturbance in the position of the hulk by the pressure of strong winds and agitated tides, the atmosphere became impregnated with mephitic gases emitted from the accumulation of impurities around her bottom. Ireland Island, where a half company of sappers was stationed, was not visited by the calamity.
