683. A peculiar difference takes place with regard to the seasons of 
the year between the interior and coastal districts : for in the former 
the change occurs but once, whereas on the coast it is repeated, so that 
in the latter one speaks of a short and long rainy and dry season 
respectively. The rainy season commences with December and con- 
tinues up to February when the small dry season follows on to April 
which again, from May to July, is interrupted by the long wet one. In 
the interior on the contrary, only one rainy season is recognised and that 
from April until middle of August. During the rainy season the land 
wind is the one prevailing: towards its end this changes into a markedly 
predominant Easterly Trade-wind which, when the day is drawing to a 
close, always becomes stronger, but by ten o'clock at night takes off again. 
Associated with this, however, the atmosphere has yet more subsidiary 
currents, particularly a sea and land breeze: the former blows from the 
north-east and cools the heat of the day, while the warm land-breeze on 
the other hand rises at night in the south-east and prevents its cooling 
too rapidly. In general the temperature of the day differs from that 
taken of a morning before 6 a.m. by eight to ten degrees. 
684. Immediately after our arrival from England the Governor, 
acting on instructions, had sent the Inspector of Police and two officers 
of the 52nd Regiment to Pirara with despatches in which England 
requested the evacuation of the village on the part of the Brazilians, a 
demand which up to now had not been obeyed. Shortly after our return 
from L’Heureuse Aventure mv brother got his marching orders at the 
same time that the Governor received instructions to send to Pirara, 
along with our expedition, a detachment of the 1st West India Regiment 
including surgeons, commissariat, two cannon, and the material necessary 
for defence purposes: they were to drive the Brazilians out by force and 
take possession of the spot invaded. 
685. This information gave new zest and put fresh life into us, and 
as we were probably saying farewell to all civilisation for several years 
to come, had to make the most varied preparations which, owing to the 
continued prevalence of fever, could not be carried out as easily as we 
wished. All the ridiculous and vexatious scenes that had already 
presented themselves during our previous preparations were re-enacted 
to an enhanced degree. One boat could not now hold the provisions and 
trade which the expedition found it necessary to take: so a second one, 
41 feet long, had to be built, and two smaller ones, second hand, from
