THE GOLD REGIONS OF THE WEST. – There can be little doubt, from the spirit now at work, that when the travel westward towards Pike’s Peak and the Pacific opens in the coming spring, there will be a large emigration in those directions. Those who design to cast their fortunes in the gold fields of Nebraska, Kansas or Fraser river, will most probably seek those regions through Missouri, and by the new road about to be opened to the Pacific through the British possessions, by way of St. Paul, Minnesota. The yet unorganized territory of Arizona, which holds forth silver promises to the adventurous, will most probably be reached through the Texas route. Two colonization and emigration companies are already in the field, offering tempting terms to those who may desire to explore the silver mines and other mineral secreta of that region, Mexico and Central America. One of these is under the management of General Henningsen, and the other under that of his quondam filibustering confrere, Col. Lockridge.
