The members of the subcommittee on hotels for the Boston session are anxious that every one shall be provided with good accommodations, either in a hotel or in a first-class boarding house. To arrange for such accommodations, however, the committee must attend to the matter before the arrival of those to be accommodated. In behalf of the committee and at its request, we urge those who expect to attend the Boston session to write to the secretary of the hotel committee, Dr. D. D. Scannell, 366 Commonwealth avenue, Boston, stating what is required. Prompt action in this matter on the part of each individual will receive prompt action on the part of the committee. Although none need fear that accommodations will not be found, even after one arrives, it is not worth while to take chances by such delay.
