28 SUFFER AN ATTACK OF BILIOUS FEVER. 
acceptable, I retired to rest, completely overcome 
with the fatigues of the day. Here I was suddenly 
attacked with a violent bilious fever, occasioned by 
my long exposure to a burning sun, while engaged 
with so much difficulty and exertion in getting the 
horses across the river, and by riding afterwards in 
damp clothes during the night, having had no op- 
portunity of changing them in the course of my 
journey.
