The launch first proceeded to Freshwater Bay, when Mr. Alpin Thomson was taken on board, with an oyster dredging net, which he kindly placed at the disposal of the Society. Some dredging was then attempted, but owing principally to the large mesh of the net, with no results save a few shell-fish and a crab.  After dredging for some time the order was given by Mr. B. H. Woodward, the indefatigable Secretary of the Society and the chief organizer of these enjoyable outings, “Full steam ahead to Peppermint Grove.” There the party disembarked, and after some slight refreshments a start was again made, this time for Rocky Bay, where the dredging was more successful, several pieces of sponge, which, under the microscope, may possibly reveal some interesting forms of animal and vegetable life, being obtained.

On the homeward journey Peppermint Grove was again touched at, to pick out some of the party who had remained on shore, and Perth was reached a few minutes before half-past six.

In spite of the partial success of the dredging operations, all were unanimous in the opinion that a thoroughly enjoyable and pleasant afternoon had been spent. The weather was perfection, and as it was the first time that several of the party had been down the Swan, they saw the river under the most favourable circumstances, and were enthusiastic in their praise of its beauties. It is intended, we understand, to make a similar excursion at some future date, when if possible a dredge specially made for obtaining specimens will be used. This evening the usual monthly meeting of the Society will be held at the offices of the Geological Department, at 7.30, when Dr. Tratman will read a paper on the insect locally known as the “chick-chick.”
