Tucson Citizen. Ancient ruins have recently been discovered in Sonora, which, if reports are true, surpass anything of the kind yet found on this continent. The ruins are said to be about four leagues southeast of Magdalena. ïhere is onc pyramid which has a base of 4,350 feet and rises to the height of 750 feet jthero is a winding roadway frorn the bottom leading up on an easy grade to the top, wide enough for carriages to pass over, which is said to be twenty-three miles m length; the outer walls of the roadway are laid in solid masonry from hugo blocks of ranite in rubble, and the circles are as uniform and the grade as regular as could be maie at this date by our best enginters. The wall, however, is only occasionally exposed, being covered over with the debris and earth, and in many places the sahuaro and otherindigenous plants and trees have grown up, giving the pyramid the appearance of a mountain. To the cast of the pyramid a short distance is a small mountain about the same size, which rises to about the same height, and, if reports are true, will prove more interesting to the archwologist than the pyramid. There seems to be a heavy layer of a species of gypsum about half-way up the mountain, which is as white as snow, and may be cut into any conceivable shape, yet sufli ciently hard to retain its shape after' being cut. In this layer of stone a peoplo of an unknown age havo cut hundreds upon hundreds of rooms, from 5 by 10 to 16 or 18 feet square. These rooms ave cut out of the solid stoce, and. so even and true are the walls, floor and ceiling, so plumb and level, as to defy variation. There are no Windows in the rooms and but one entrance, which is always from the top. The rooms are but eight feet high from floor to ceiling; the stone is so white that it seems almost transparent, and the rooms are not at all dark. On the walls of these rooms are nunierous hieroglyphics and representations of human forrus, with hands and feet of human beings cut in the stone in different places. But, strange to say, the hands all have tive fingers and one thumb, and the feet havo six toes. Charcoal is found on the floors of many of the rooms, which would indícate that thev build fires in their houses. Stone" implements of every description are to be found in great numbers in and about the rooms The houses or rooms aro one above the other, three or four stories high, but. between each story there is a jog or recess the full width of the room below, so that they present the appearance of large steps leading up tho mountain. Who these people were and what age they lived in must be answered, if answered at all, by the "wise men of the East." Some say there wero the ancestors of the Mayos, a race of lndians who still inhabit Southern Sonora, who have blue eyes, fair skin and light hair, and are said to be a moral, industrious and frugal race of people, who have a vvritten languago and know something of malhematics.
