colonies of them in like manner were afterwards propagated in 
different parts of the ifland by droghers, or veflels employed in 
carrying dores, &c. from one part of the ifland to another. 
From thence they continued to extend themfelves on all 
Tides, for feveral years ; dedroying in fucceflion every lugar 
plantation between St. George’s and St. John’s, a lpace of 
about twelve miles. At the fame time, colonies of them 
began to be obferved in different parts of the ifland, particularly 
at Duquefne on the north, and Calavini on the fouth fide 
of it. 
All attempts of the planters to put a dop to the ravages of 
thefe infeCts having been found ineffectual, it well became the

the cultivation of the fugar- cane as formerly. Accordingly,
