Yesterday on the river the class crews enjoyed for teh first time this season fair weather and comparatively smooth water. There are now two freshman crews, the second crew, however, consisting of only six men. Following are the names of the men trying for positions:- First crew: Stroke, Bishop; 7, Randall, 6, Longworth; 5, Longstreth; 4, Cumnock; 3. Hammond; 2, Williams; bow, Wood-worth. The second crew, lacking numbers 5 and 6, is composed as follows:- Stroke, Parker; 7, Tudor; 4, Amory; 3, Winthrop; 2, Bangs; bow, Lawrence. The '88 crew is at present rowing in the following order:- Stroke, Hale; 7, Butler; 6, Bradlee; 5, Appleton; 4, Porter; 3, Churchill; 2, Crocker; bow, Tooker. The '89 crew is made up of-stroke, Perkins; 7, Parker; 6, Hobard; 5, Perry; 4, Dustan; 3, Hight; 2, Keyes; bow, Smith. The '90 crew are rowing in the following order:- Stroke, Herrick; 7, Hutchinson; 6, Hartridge; 5, Sanford; 4, Sturgis; 3, Tyson; 2, Crowinshield; bow, Crehore. The crews, with the exception of the freshmen, are beginning to get into good form and keep time together. The crews seems to be pretty evenly matched, and there is every reason to expect a close and exciting finish at the class races next May.
