OBSERVATIONS. 
477 
estimated at 220^. It comprised 
3 marquees and 4 tents, and some 
other equipments. Captain Trotter 
is desirous of having this doubled, or 
nearly so, and we think the request 
is reasonable. 
We recommend it therefore for 
approval. 
5. Upon particular inquiry upon 
this head, we find that Mr. Brumel, 
whose authority may be deemed of 
great weight, is of opinion, that cir- 
cular saws attached to a portable 
steam-engine, would be so liable to 
get out of order, that the machine 
would be useless for the purpose in- 
tended. 
Mr. Laird is also of this opinion, 
and says that the ventilation fan 
may be worked by two men by 
hand. 
Under these observations, Captain 
Trotter wishes to omit the portable 
steam-engines, and the more particu-

ventilating the vessels may cost much 
more than he was led to anticipate. 
Mr. Brumel approves 
the plan of ventilation 
proposed by Dr. Reid, as 
explained by Mr. Laird ; 
and under the observa- 
tions on the opposite half 
of this page, this item 
would be thus modified : 
For fans forventilation, 
and wheels for each ves- 
sel, estimated by Mr. 
Laird at about 35?. each 
say 
£105 
For tubes for 
each vessel for 
ventilation, about 
100?. each 
300 
For additional 
fittings up, say 
For expenses 
of Dr, Reid, in- 
cluding remune- 
ration to him for 
95 
his services 
100 
£600 
It may here be ob- 
served, that in the Expe-
