29. Gaudelapepita.--At 5 miles the road ascends to the dividing ridge, and is tolerable; thence in 4 miles cross the mountain, and reach a fine spring branch, where is a fine camp. Thence the road passes short ridges for 9 miles to Black Lake. Good camp. Fort Union.--Road follows Coyote Canon 3 miles; thence one mile to Mexican settlement; thence 19-1/2 miles over the prairie to the fort. * * * * * Colonel Loring came over the route from Camp Floyd to Fort Union with a large train of wagons. He, however, found the road in many places upon the mountains very rough, and it will require working before it will be suitable for general travel with loaded wagons. It is an excellent route for summer travel with pack trains, and is well supplied with the requisites for encamping. From Fort Union to Fort Garland the road passes through a settled country, where supplies of grain and vegetables can at all times be purchased at reasonable prices, and there are small towns met with during almost every day's march where small shops supply such articles of merchandise as the traveler needs. * * * * * XXVIII.--_Wagon-route from Guaymas, New Mexico, to Tubac, Arizona._ From Captain STONE'S Journal.
