Herbert George Wells and the Grenadines

I was somewhat surprised to find that H. G. Wells had mentioned the Grenadines, and St. Vincent as well, in 1894, in his short story "Mr. Ledbetter's Vacation". Google turns it up in several places including [http://www.readprint.com/work-1493/H-G--Wells#logo]. It is a very brief mention, with no description, but it was still an odd thing to run across.
