F: Darwin, H. O. Forprs, G. C. Bourne, A. R. Binnie, J. C. 
HawksHaw, and Hon. P. Fawcett, appointed to consider a project 
for investigating the Structure of a Coral Reef by Boring and 
Sounding. 
As mentioned in the report presented to the Ipswich meeting, the 
Council of the Royal Society had inquired from the Admiralty whether 
the Government would be able to assist an expedition by putting a sur- 
veying vessel at its disposal. In the course of the autumn a reply to this 
inquiry was received to the effect that My Lords would be willing to 
convey the members of the expedition and their apparatus, as far as pos- 
sible, to Funafuti, which had been already suggested as a favourable spot 
for the investigation. A grant of 800/. was made from the fund placed 
by Government at the disposal of the Royal Society, and a further grant 
was made from funds administered by the’ Council, with the result that 
Professor Sollas, with Mr. Stanley Gardner, of Cambridge, as naturalist, 
and assistants from Sydney, sailed from that harbour in H.M.S. ‘ Penguin,’ 
commanded by Captain Field, on May 1. But, even with the above 
assistance, the expedition could not have been sent had it not been for the 
great help given in Sydney by Professors Stuart and David, by Mr. W.H. 58. 
Slee, Chief Inspector of Mines, and by the Department of Mines of New 
South Wales. It is due to them that boring tools and workmen have 
been lent by that Department, with the result that the cost of the under- 
taking has been practically halved. 
News has been already received from Professor Sollas. The first 
attempts unfortunately proved unsuccessful, as a quicksand was struck, at 
a depth of about 65 feet, which choked the machine ; but fresh apparatus 
was on its way from Sydney, and it was hoped that more favourable 
results would attend the next trial. The news of that is expected shortly. 
The grant of 10/. was drawn and applied towards the necessary expenses 
preliminary to the expedition. As the cost of the undertaking is almost 
certain to exceed the sum granted by the Royal Society, the Committee 
suggest that a liberal grant be made in aid of the boring, and that it be 
placed in the hands of a small committee.
