This was produced from a copy o f a docum ent sent to us for microfilming.While the most advanced technological means to photograph and reproduce this docum ent have been used, the quality is heavily dependent upon the quality of the material submitted.The following explanation o f techniques is provided to help you understand markings or notations which may appear on this reproduction.■ I.T h e sign or "targ et" for pages apparently lacking from the docum ent photographed is "Missing Page(s)".If it was possible to obtain the missing pagc(s) or section, they arc spliced into the film along with adjacent pages.This may have necessitated cutting through an image and duplicating adjacent pages to assure you o f com plete continuity.2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed cither blurred copy because o f m ovement during exposure, o r duplicate copy.Unless we m eant to delete copyrighted materials th a t should n o t have been filmed, you will find a good Image o f the page in the adjacent frame.If copyrighted materials were deleted you will find a target n o te listing the pages in the adjacent frame.3. When a map, drawing or chart, etc., Is part of the material being photo* graphed the photographer has followed a definite method in "sectioning" the material.It is custom ary to begin filming at the upper left hand corner o f a large sheet and to continue from left to right in equal sections with small overlaps.If necessary, sectioning is continued again-beginning below the first row and continuing on until complete.4.
