buried. 
Kasongo was left on April 27, 1905. The journey thence to Pania 
Mutombo lay overland and was done on foot. Kalombe was reached 
on May 3, Maomedi on May 5. No stop of more than a day was made 
before reaching Tshofa (May 13 to 25). Four days, June 2 to 6, 
were passed at Cabinda. At Pania Mutombo (June 12) canoes were 
once more employed for the two days' journey down stream to 
Lusambo (June 5), where the expedition remained until July 8, 1905. 
The journey from Lusambo to Leopoldville was done as quickly 
as possible by steamer, and no stops were made for work. At 
Leopoldville (July 21 to 30) arrangements were made for leaving Afrit .1 
The railroad between Leopoldville and Matadi was once more 
traversed, and on August 8, 1905, the expedition left the Congo Free 
State. On the way home Freetown, Sierra Leone, was visited for a 
week (August 16 to 22). Liverpool was reached on September 5, 11/ 5 , 
the expedition had been absent from England for just two years 
Other side-trips were made besides those mentioned ; and it must 
be understood that when a stay of any duration was made in a post 
short journeys were always made in its neighbourhood. 
As is shown by the map, the route followed by the expedition 
twice crossed the equator and traversed a territory King between 
2° North and 6° South of that line. The climates of the posts visited 
therefore varied somewhat. The succession of the seasons at the 
most important places is briefly as follows: 
At Boma the seasons are irregular. There is usually said to be .1 
long and a short wet, and a long and a short dry, season. Practically, 
we may say that from May to September there is but very little 
or no—rain ; and that from October to the end of April there is a 
good deal; from January to April are the hottest months of the year 
It is then, from October to May that conditions are the must 
favourable for the breeding of mosquitoes. At Leopoldville rain 
more likely to fall in every month of the year than at Boma. 1 o m 
the 15th of June to the 1st of September is usually considered to 1 ><• 
the dry season, and during this period there may be practically no rain 
Coquilhatville is almost on the equator, and consequently has m 
marked variation in its seasons. Rain falls in ever)- month u! tin* 
year, perhaps the most in November and December The
