Storrow, Mr. C. A. W. Bargoyiie, Mr. A. E. Hefford, Mr. A. J. 

 Brander, Mr. R. B. Marston, Mr. J. A. Eobertson, and my 

 friend and colleague Mr. R. Jackson, who have each read all 

 or part of the MS. and given me much advice, encouragement, 

 and assistance. If I have anywhere appeared to borrow or 

 steal ideas without acknowledgement I apologize here and 

 now, and renounce all claim to the property. What is good 

 in the book is the work of other people. The mistakes are 



my own.
