GATE OF THE MONKS.

"We crossed the plaza and continued on to the Postiga de las Monas, or 'Gate of the Monks,' which is crowned by a watch-tower, and leads through the ruined wall to the beach. A woman and child were sitting under the shadow of the gateway, and people were coming and going, on foot or in the saddle. When we reached the beach the tide was out and there was a large expanse of coral reef visible; it was alive with crabs, shrimps, cuttle-fishes, and other marine products, and we picked up lots and lots of shells of curious form and color. It is a splendid place for conchologists, and if the sun had not been so hot we would have stayed there an hour or two.

RUINS OF CHURCH OF SAN DOMINGO.

"We came back through the gateway, and met one of our late companions of the train. He took us to see the ruins of the Church of San Domingo, which was built soon after the founding of the city, and burned more than a hundred years ago. In its time, it was the finest church in Panama, and was said to possess a great store of silver and gold images and other treasures.

REMARKABLE ARCHWAY.

"Dr. Bronson was anxious to see a remarkable arch which was said to exist in the ruins of the church, and our friend offered to point it out. We passed among the walls, which were thickly overgrown with vines and bushes, and finally came to the archway. It is forty feet long, and has a perpendicular radius at the keystone of only two feet; it is made of brick, and is said to be a wonderful piece of work. Our friend said he had never heard of anything like it, and that many architects passing through Panama in the last twenty years had seen and admired it.
