Translation - French to English

I have a pdf article from a journal from 1967 or 1968 that is written in French. It is a page and a half long with a map, about 14 paragraphs. I need to have it translated into English. I am using this article as a reference for the book I am writing. I used Google Translate on it, and only have of the English is decipherable. The pdf is 64 MB, not sure why since it is pdf and only 1 and a half pages. So too large to attach.
