l Wash the outcropping reef or band ol 1 cclcstite was paced and found to be l about seVcntN-fiVc feet thick. This Cutcrop. il is explained. is not pure l oclcstite, but it is more than probable l that the pure mineral will be found i in some places in thin bands and ~treaks and in others more or less | intimately mixed with other sub i 1tancc~-for example, gypsum, quartz
 in the form of sand or chaIcedony, i clay. and the oxides of manganese
 and iron
 1 The ccIestite deposits in Arizona visited by AIr. Phalcn are fifteen miles south of Gila Bend. Maricopa l county Here the celestitc occurs in i the form of a bed or beds ovcrlaid
 and undcrlaid in some places by sandstone beds and in others by ign l cous flows. In the northwestern part
 of tho deposit. where the relations and thicknesscs can be best deter
 mined, the bed with which the celes- ! titc is directly associated is forty l to fifty feet thick. Of this thickness i the upper eight feet to ten feet look ! cd most promising as source of the mineral. Careful prospecting, 1 however. will be necessary to deter 1 mine the thickness and extent of the 1 purer layers of the mineral

 Outside of the discovery south of GiIa Bend, I think it gill also be found along the Colorado river. cs- rcciaIIy in the old silver district of 1 Castle Dome where silver lead ores
 have been mined for many years.
