PANAMA CANAL. ment. The shore at this point is occupied by docks and coal storage with which any extraneous structure would come in conflict. More- over, there are points of interest as one approaches the canal from the Pacific with which it would be unwise to attempt to compete by any structure built for artistic reasons alone. The shore itself, with its rugged range of mountains, is inspiring, and the islands guarding the entrance are interesting in the extreme. The islands to the south really will guard the entrance, as three of them are to be occupied by forts with heavy guns. The second one, Perico, is most unusual and picturesque. Naturally a wooded mound, rising abruptly out of the sea, the top has been flattened for a fortress, and a spiral road- way encircling the island leads up to it from the causeway which connects this island with its neighbor, Naos, and thence with the mainland. In our opinion, the only place upon which a monument might be erected would be on the small round hill at Point Farfan, which rises directly from the water at the entrance to the canal, and is symmetrical in form. It would, however, be difficult to erect any structure here that would not appear to be forced unless it were a lighthouse, and the plan for lighthouses and beacons does not pro- vide for a light on this eminence. All things considered, we are not prepared to advise adding any structure to those already projected at the south end of the canal. 6. THE ISLANDS OF NAOS, PERICO, CULEBRA, AND FLAMENCO. These islands, referred to above, are, as already stated, connected with each other and with the mainland by dikes or causeways. (See photograph, Exhibit No. 12.) One of these causeways between East Balboa and Naos is about 3:- miles in length, and as it may come to be a favorite drive for the people of Panama it has been proposed to plant it with trees throughout its entire length. If the trees were planted near enough together to shade the road effectively they would completely shut out from the ships entering or leaving the canal the view of the city, which at present is very attractive. They might also disturb the effect of the long low straight line which the causeway now makes and which is a striking note in the picture, and they would tend to make the shore continuous with the island, and thus destroy the effect of its being an island. We therefore doubt the wisdom of such tree planting. It may be possible to plant groups of trees, presumably palms, near the ends of the causeway without impairing its effect and the impression of Naos Island. This should be carefully considered. The same arguments apply to the dike connecting Naos and Perico, though not to the same extent. 7. PERMANENT TOWNS. After the completion of the canal the work of maintenance and operation will require the residence of a considerable permanent population of employees on the Canal Zcne. It is expected that these will be concentrated at five centers. Four of these are now occupied by the construction force, and at these it is proposed to utilize the present quarters, as far as available, with such gradual replacements and changes as may prove necessary. These are: (1) Cristobal and Colon, chiefly for those concerned with the port, with the sea-level
