In this hrief article the author calls attention to the mining districts 
of Texas, viz. : the Trans-Pecos region and the central district, which

pointed out. Among the properties worthy of mention are the Shatter 
mine (ten stamps; silver and galena), the Hazel mine (silver-bearing 
copper ores — ^sulphides) ; the Bonanza and Alice Ray mines (argentiferous
