Mr Stevenson’s books have taken a permanent place in engineer- 
ing literature. Amid the exacting calls of his profession he found 
time to write many papers on engineering and cognate subjects, in 
addition to the books already noticed. He also wrote several 
articles for the last and the present editions of the Encyclopedia 
Britannica , among which may be noticed “ Canal,” “ Cofferdam,” 
“ Diving,” and {£ Dredging.” He was also the author of Our Light-
