PORTSMOUTH — Christina West, 63, of Lawton Brook Lane, was in fair condition yesterday in Rhode Island Hospital, four days after the horse-drawn carriage she was riding in struck a stone wall and tipped over at the Carnegie Abbey sporting club last Friday afternoon.

West’s four companions on the ride told the police that the horses pulling the buggy somehow became spooked.

Marjorie T. Grafton, 59, of Unionville, Pa., the driver, told the police the animals stopped responding to the reins and began galloping, turning a corner off a dirt road into a wooded area and pulling the carriage along with them.

When the buggy struck the wall and tipped over, the horses were still attached to their harnesses, the police said.

When they arrived, the police said, they found West lying in the dirt up against a tree, with another passenger, Terrence Leigh, 29, of West Grove, Pa., applying traction to mitigate West’s injuries.

The horses were removed safely by the staff of Carnegie Abbey, according to a police report.

The police said Portsmouth and Tiverton rescue squads attended to West and two other passengers who had been injured in the accident, Michelle M. Kirby, 49, of Ashurst Drive, Middletown, and Kathleen K. Greenman, 54, of Paradise Avenue, Middletown.
