Volume 20 was published in 1911. Its articles run from markets to misrepresentation. It contains articles on markets and fairs (59 pages), master and servant (221 pages), medicine and pharmacy (82 pages), the Metropolis (106 pages), mines, minerals and quarries (156 pages) and misrepresentation and fraud (110 pages). According to the "Harvard Law Review", the article on master and servant was of constant interest to an American lawyer; and that on misrepresentation and fraud, from the master hand of G Spencer Bower, was a valuable treatise in itself.
