It is unknown if this survey was published, or if it was, where it was published. This copy may be one of the only remaining copies in exsistence. Unfortunately this copy may be a draft as there are some comments in the margins and numbering of figures/tables are off. But this was an incredibly detailed and useful study and we feel that this warrents posting this report "as-is".
