This reprint is a facsimile scan of the original 1922 document published by George H. Doran Company. Other reprints of this document have used the OCR (optical character recognition) and many errors are found in the text. We elected to go a further step to scan and remove the background color image to further enhance and sharpen the page. We have enlarged the borders to accommodate the presentation of the entire original pages including the original borders and page numbers. In order to maintain integrity of the original page numbering , table of contents, and indexes, we have left these intact. For this reason you will see two page numbers on each page. One page number is from the original document. We have added a second page number at the bottom of each page to aid the reader. Other than removal of page color and the removal of blank pages, the document is exactly as the original.
