at home as well.
The use of a narrative to connect the various incidents marks a departure in this class of book, and it is believed that the matter will thus be made more realistic and interesting. In all cases full directions are given for making the various articles. While it is not presumed that the directions will be slavishly followed, for this would defeat the general aim of the work, yet all the principal dimensions are given so that they can be used, if desired.
I beg to acknowledge the courtesy of Mr. Daniel C. Beard and Mr. Henry D. Cochrane in supplying a number of photographs. The directions for making the lee boards (page 119) were obtained from data furnished by the latter. Many of the details recorded in the chapter on Tramping Outfits are to be accredited to Mr. Edward Thorpe. In the preparation of this book I have received valuable assistance from my colleague, Mr. A. A. Hopkins.
