5.H.3. PATH FORMING PUZZLES
Here we have a set of pieces and one has to join them so that some path is formed. This is often due to a chain or a snake, etc. New section. Again, Haubrich's 1995-1996 surveys, op. cit. in 5.H.4, include this as one class.
Hoffmann. 1893. Chap. III, No. 18: The endless chain, pp. 99-100 & 131 = Hoffmann Hordern, pp. 91-92, with photo. 18 pieces, some with parts of a chain, to make into an 8 x 8 array with the chain going through 34 of the cells. All the pieces are rectangles of width one. Photo shows The Endless Chain, by The Reason Manufacturing Co., 1880-1895. Hordern Collection, p. 62, shows the same and La Chaine sans fin, 1880-1905.
Loyd. Cyclopedia. 1914. Sam Loyd's endless chain puzzle, pp. 280 & 377. Chain through all 64 cells of a chessboard, cut into 13 pieces. The chessboard dissection is of type: 13: 02213 131.
Hummerston. Fun, Mirth & Mystery. 1924. The dissected serpent, p. 131. Same pieces as Hoffmann, and almost the same pattern.
Collins. Book of Puzzles. 1927. The dissected snake puzzle, pp. 126-127. 17 pieces forming an 8 x 8 square. All the piece are rectangular pieces of width one except for one L hexomino -- if this were cut into straight tetromino and domino, the pieces would be identical to Hoffmann. The pattern is identical to Hummerston.
