In the American Political Science Review of August, 1907, Mr. Lapp made a comparison of the public service commission laws of New York and Wisconsin. Since that time the laws of the two states have been amended and other states have adopted similar laws. On request, Mr. Lapp has revised his comparison and brought it down to date for the Legislative Reference Dept. of the Ohio State Library. This is published for the use of the General Assembly.--Cf. p. [3].
