Eastern Echo, who was getting ready for his first year at Maryland Stallion Station near Glyndon, Md., after standing at Shamrock Farms near Woodbine, Md., died Tuesday morning of a heart attack."He was feeling fine beforehand, and we were looking forward to the new breeding season at the new farm," said a representative of Maryland Stallion Station (Don Litz, president). "He had a great disposition and was very fertile."Eastern Echo, a homebred grade I winner for the late Paul Mellon, began his stallion career at William S.
