As the title indicates, the book deals only with co-operation in the New England states. The author further limits his research to “associations for the production and distribution of the immediate necessities of life.” Notwithstanding this limiting of the inquiry both in scope and extent the book should prove of value to the student of co-operation in this country. The facts have been painstakingly collected. The author’s insight is keen and penetrating, his deductions are clear and logical, and his hopeful tone is most invigorating. LEONARD G. ROBINSON. THE CASE OF OSCAR SLATER By A. CONAN DOYLE. George H. Doran Co. 103pp. Price $.50; by mail of THE SURVEY $.57. The case of Oscar Slater, sentenced in the High Court of Edinburgh to life imprisonment for the murder of an old lady in Glasgow, was some time ago brought to the attention of the famous writer of detective stories, together with certain circumstances which cast doubt on Slater’s guilt. With a sincere desire to clear the man, the creator of Sherlock Holmes set to work to examine the evidence and testimony presented at the trial, and to analyze the conduct of the case and the decision of judge and jury. The result is a convincing argument for the man’s innocence of the offence for which he was convicted and an arraignment of the ineffective methods of the police who were engaged in the investigation, both in Scotland and in this country. The undeniably bad character of the suspect created so strong a presumption of guilt that even the total refutation of the strongest piece of evidence and an obviously false accusation by the judge in his final charge, secured only a commutation of the death sentence to life imprisonment when an appeal was made. It will be interesting to know whether the detective knight’s efforts toward securing justice meet with success. MAY LANGDON WHITE. PERSONALS The first woman judge of delinquent girls sits on the bench in the Chicago Juvenile Court. She is Mary M. Bartelme, a Chicago lawyer. Previous to her present connection she was for eighteen years public guardian of Cook County, acting in this office, in the words of the _Continent_, as “official mother to hundreds, perhaps thousands, of children” who had no other parents and whose persons or estates were in the care of the court. Guardianship of their persons meant actual custody and education, and this for a period of many years; it meant also in many cases interest and love for the child and always, in the tangled relations of life, an understanding of human nature, as well as a thorough knowledge of the institutions best fitted for special cases. All this experience has thus been excellent preparation for Miss Bartelme’s present delicate task of reconstructing the lives and characters of delinquent girls. [Illustration: MARY M. BARTELME]
