The Hooghly left Plymouth 3 July 1846 and passengers disembarked in Adelaide South Australia Saturday 24 Oct 1846. The official passenger list appears to have been lost. Below is an extract from The Register newspaper of Wednesday 28 Oct 1846 concerning the arrival of this vessel as well as the passenger list published elsewhere in the same paper. This is of interest because it clearly states the bulk of the Hooghly passengers have been brought out by the English Mining Company to work as miners, labourers and domestic servants. Other records suggest the company was actually the Australian Mining Company, head office London.

The passenger list has been sorted alphabetically for ease of manual searching, rather than presented in the somewhat mixed up fashion as originally printed in the SA Register on Wednesday 28 Oct 1846.

The following news leader together with the shipping in our back page appeared on Monday as a second edition to our impression of Saturday, "Register" Office, Monday Morning 26th October 1846

ONLY once before has the colony been greeted by the arrival of four English ships in a day; but it was a memorable occurrence; and so we esteem that which we now record, couple as it is with a renewal of emigration to some extent, although the present and prospective arrivals will be but as drops in the bucket compared with the almost unlimited demand for labour in town and country. The intense interest created by these arrivals, which we announced in quick succession, on Saturday last, whilst our press was yet at work, and which would have stopped if it had been possible to obtain sufficient particulars from the Gulf, has induced us to depart from our usual routine, and to anticipate our Wednesday's issue, by the publication of a second edition, this morning.

After an unusual detention by the prevalence of adverse winds, we have gratification to announce the arrival, at the wharf, of the following ships, namely,
the HOOGHLY from London and Plymouth (July 3rd),
with 240 cabin passengers and emigrants;
the BRITANNIA, from London (June 6th)
with 141 passengers;
the GUNGA, from Liverpool, (June 27th)
with one passenger;
and the TAGLIONI, from London (June 27th),
with three passengers.
In addition to these arrivals we must not forget to announce that of the beautiful colonial-built RAVEN, from Launceston, with a cargo consisting chiefly of building materials and nine passengers, besides twelve horses.

Thus have nearly four hundred souls been added to our population in the short space of twenty four hours. The number of professed mechanics included in these new colonists is remarkably small. They seem to consist of agricultural labourers, or persons accustomed to country work. There are, however, about twenty miners (thirteen of whom are specially engaged for operations upon the lands of G.F. Angas, Esq.) and a good sprinkling of female domestic servants. The emigrants, per HOOGHLY, with those who have preceded them, make up 500 sent out by the English Mining Company; and they are to be followed by 300 more from that Company.

In addition, however, to the arrivals we have just described, we may hourly expect from London the SYMMETRY, full of passengers and goods; and, shortly, the AUGUSTUS, which was to sail three weeks after the Hooghly. On the 1st of August the ROYAL ARCHER was to sail from London for this port.

On the 25th July the Government emigrant ship LADY BRUCE, 600 tons, was to sail with free emigrants, and a number of cabin passengers.

Besides these, the SYREN, 300 tons, from Guernsey, was due to leave the Channel Islands positively on the 1st August, 1846 with a full cargo. It seems that no passengers were on board the SYREN when it arrived in December 1846 from Guernsey (Ref. Ron Parson's MIGRANT SHIPS FOR SA 1836-1860)

were also bringing emigrants from London.

During the summer months, three vessels a month arrived in Adelaide, South Australia from overseas,
one in each month being an emigrant ship.

The SPARTAN, via Port Phillip,
arrived at Gravesend May 20th,
having on board a large quantity
of Burra Burra copper ore.
The JOHN HEYES, with a similar cargo
and the Bishop of Adelaide as the principal passenger,
arrived home on June 28th;
and the AMELIA, with the first cargo of ore
direct to Swansea,
had arrived there (at Gravesend).
