The web pages you want to download takes up about 11 MB of disk space. 

Yes you can download <http://www.sil.org/americas/suriname>, I just succesfully
did so. 

To limit the downloading to the desired parts of sil.org, I would use a filter
such as:

-* 
+http://www.sil.org/americas/suriname/*

(in that order)
