A steamer of the Bull line runs between ports in Santo Domingo and Porto Rico and there is also a coast line under Dominican registry, which extends to Porto Rico, but the steamers of which do not distinguish themselves for comfort. Thus there is at present frequent steamer service between Santo Domingo and Porto Rico, but little communication with Haiti and Cuba. Most of the steamer lines touching in the Republic carry mails. Santo Domingo is a member of the International Postal Union and its post offices offer the usual facilities, except that there is no money order system. More than three-quarters of the incoming foreign mail comes from the United States, including Porto Rico, and over one-half the outgoing foreign mail is directed to this country. The American authorities are engaged in a thorough re-organization of the Dominican postal service. In connection with the post offices the government operates a telegraph and telephone system. The government lines connect all the more important points in the country. Constructed without plan or method and insufficiently cared for, these lines are all in poor condition and badly in need of repair or reconstruction. The charges are high and the service poor. The government also has a wireless telegraph station at Santo Domingo City and another at Macoris. The French Submarine Telegraph Co. affords Santo Domingo cable connection with the rest of the world. Its cable touches at Puerto Plata and Santo Domingo City, crossing the Republic by means of a land line which is also open to local messages. The interruptions of communication over this land line in the various revolutions have given rise to numerous damage claims on the part of the Company. There are also telephone lines on the Samana-Santiago Railroad and on the Central Dominican Railroad operated in connection with the respective roads. Local public telephone systems are in operation in Santo Domingo City and San Pedro de Macoris, and there are private telephone lines between the principal cities and plantations in their vicinity.

The fact that Dominican commerce has more than trebled in twelve years demonstrates the epoch-making character of the fiscal convention with the United States. The trade figures since 1905 are as follows: GROWTH OF DOMINICAN TRADE (All figures are in American currency) Imports Exports Total
