to ‘thousands’ (...thousands of
     laboring men... )
   Page 205:  added ‘s’ to ‘brick’ (thousands of bricks)
   Page 212:  added " to para beginning ("Viewed from the railroad ...)
   Page 212:  added ‘s’ to ‘thousand’ (Thousands of travellers ...)

Also added:  Periods and commas, various (in the poetry footnotes).  The text appears worn; there is space for a period (and a couple of letters are missing), so I am assuming that the missing punctuation may have been rubbed off the page.

I have also encountered a number of instances throughout the book where the author quoted from an external source and omitted either the opening or closing quotation mark, and it is not obvious from the text just where the quote began or ended.  In a couple of instances I have hazarded a guess, but have otherwise left the single quotaton mark in place, as it appears in the original.]
