Hermosillo is situated on the Sonora River, in the midst of an agricultural district and surrounded by rugged mountains, where there are many mines of gold and silver. It is the seat of a Catholic diocese, for which a fine new cathedral has been built, and also has some very creditable buildings. It is a city of perhaps ten or twelve thousand people, and is the largest city in the state. From Hermosillo this railroad runs to the port of Guaymas, which is quite an important commercial town, and less than a hundred miles from the capital. The Bay of Guaymas is one of the best on the Pacific coast, and the marine trade is quite important. For a long time this town was the terminus of this railroad, but it is too far up the Gulf of California to ever become a very important ocean port. Within the last few years construction work has been rapidly pushed southward at a little distance from the coast, and through trains are now running as far as the city of Tepic, on the way to Guadalajara. Not a great distance south of Guaymas the Sonora Railroad enters Sinaloa, a state nearly as large as Indiana. This state is destined to be a great agricultural state, as it is well watered and contains a number of fine rivers. Besides the Fuerte, Sinaloa, Culiacan and Elota Rivers, there are a hundred or more smaller streams traversing it. It stretches along the Pacific coast for a distance of nearly four hundred miles, and has an average breadth of eighty miles. One-half of the state is little known, and is traversed only by obscure and difficult trails. Cane and corn culture have been the chief industry, but it offers good inducements for the raising of almost all kinds of grains. In undeveloped natural wealth, both agricultural and mineral, and in its splendid water powers, Sinaloa is unsurpassed by any Mexican commonwealth. An American land company has recently opened up a tract of two million acres, and is establishing a colony that promises good results. The capital is Culiacan, a short distance from the coast. Heretofore the only outlet for this city of fifteen thousand has been a miserable railroad to its port, Altata, but the new line enables passengers to go by Pullman cars to all points in the United States. It is an old city, for the Spaniards found a considerable settlement there. They immediately established a town which was well fortified. The present city is quite attractive and possesses a little manufacturing. It is the residence seat of quite a colony of rich and cultured Mexicans, and a number of Americans interested in mining also reside there.
