Captain Trotter states it 
would be essential to lay down 
oil-cloth between decks to pre- 
vent the necessity of wetting 
the decks, the expense of which 
he estimates at . .100 
£1000 
should even at the pre- 
sent cost, make the clie- 
mux - de -fri&e, and felt 
the boilers, and from the 
experience he has had of 
Mr. Laird, he believes the 
increased estimate is in 
other respects likely to be 
correct. 
See on this point Cap-

employed on land journeys, these 
portable boats may be most useful. 
It does not appear that they would 
otherwise be requisite. One boat, 
however, will be wanted as a life* 
boat ; and this should be a superior 
boat. 
As we apprehend that the Com- 
missioners are not to be employed 
on land journeys, we recommend that 
the life -boat only be got under this 
item of expenditure. 
Captain Trotter presses for an 
additional number of tents, in which 
to put his men under cover on shore, 
thus separating the sick from those 
in health.

Under the observa- 
tions on the other half of 
this page, this item would 
be thus modified : 
For one superior life- 
boat, from 80?. to £100 
For additional 
camp equipage,
