All precedents for early rowing on the Charles may be shattered this afternoon if present plans for taking some oarsmen out in the Leviathan materialize. Last Friday, Coach Stevens and Spuhn led a squad of oarsmen in clearing the ice from in front of Newell boathouse, and with the rain last night it is probable that squads will take the river this afternoon under the direction of Coach Brown. The river is clear below Weld boathouse at present, but there is no thought among the coaching staff to launch any shells until later in the spring.
