At Iloílo the dredging of a fifteen-foot channel up to the custom-house was completed in March, 1907. Seven hundred and eighty-three feet of river wall and twelve hundred ninety feet of reënforced concrete wharf, both to accommodate vessels of eighteen feet draft at low water, have been built along the south bank of the middle reach of the river. The lower reach has been dredged to twenty-four feet at low water, the middle reach to eighteen feet and the upper reach to fifteen feet, while two hundred ten thousand square metres of land have been reclaimed and two hundred six thousand improved with the dredged material. Wharves for ocean-going steamers should ultimately be constructed at this important port. At Paracale, in Ambos Camarines, a reënforced concrete pier four hundred ninety feet in length has been built. It extends out to a depth of fifteen feet at low water. At Bais, Negros, a timber pier for vessels of sixteen feet draft, with a stone causeway approach a mile and a half in length, and a warehouse for the temporary storage of sugar, have been constructed. Channels have been blasted through the coral reefs surrounding the islands Batan, Sabtang and Itbayat in the Batanes group, where the annual loss of life had previously been great, owing to the occurrence of sudden storms which often made it impossible for people to return to their towns through the surf. The port of Pandan, in Ilocos Sur, has been improved by means of a stone revetment twenty-nine hundred seventy-five feet in length along the north bank of the Abra River, thus maintaining the channel in one position and affording vastly better means of loading and discharging cargo for the important town of Vigan. A self-propelling combination snag boat, pile driver and dredge for the improvement of the great Cagayan River has been built, and is now in operation on that stream. Very numerous other works of repair and construction have been carried out. Some 80 surveys have been made in minor ports to determine the feasibility of improvements, and in many cases plans have been prepared for proposed work. The Spaniards had devoted much time and study to a project for coast illumination. At the outbreak of the insurrection in 1896 they had twenty-eight lights, fourteen of which were flashing and fourteen fixed minor lights, while four additional stations were under construction. Then all work was stopped, and when systematic inspection was made by American lighthouse engineers five years later, extensive repairs were found to be necessary. The repairs were made as promptly as possible, and new construction then began. To-day there are a hundred forty-five lights in operation, and the waters of the Philippines are among the best lighted in the world. One hundred and eleven buoys of various classes are being maintained. The following table shows the progress made in the construction of lighthouses:--
