New York, April 19- Miss Alice Farnam Leader, a New York physician escaped from the Titanic on the same boat which carried the Countess Rothes. " The countess is an expert oarswoman." said Dr. Leader, " and thouroughly at home on the water. She practically took command of our boat when it was found that the seamen who had been placed at the oars could not row skillfully. Several of the women took their place with the countess at the oars and rowed in turns while the weak and unskilled stewards sat quietly in one end of the boat."
