A comparison between the numbers of Gambusia in the natural 
bayou and in all other classes of water shows an average of 25 speci- 
mens for each collection in the bayou and an average of 63 per 
collection for all other places. These figures indicate that these little 
fish are very abundant and very generally distributed in the region. 
The larger average per collection for all classes of water, as compared 
with the natural bayou, is explained by the fact that certain collec- 
tions were made at the season of low stages of water which found 
these fish highly concentrated in some locations. 
CLEARING THE BAYOU. 
The clearing of the bayou was done during August, 191. It was 
accomplished then for the reasons that the water in the stream was 
at its lowest level and that the plantation had finished its cultivation 
of the crops but had not as yet begun to harvest. This plan gave 
minimum water conditions and a supply of labor for the work with- 
out interference with the plantation operations. The smaller under-
