FUTURE AND PRESENT ON
 WEST COAST IF MEXICO
(By John H, McCutchen)

While the state Of Sinaloa may lead the state of Sonora in the numDer Of acres available for reclamation for agricultural and horticultural pur- poses, Sonora as surely leads Siua- loa in the mineral possibilities upon development. Sonora also shows mere real development in it's differ ent mineral districts, and a greater area of mineral country. But this does not mean that Sinaloa is not T great mining state, and it must also be taken into consideration that the west coast country includes ali that part of the Sierra Madre range best rcached from the town and seaDorls of the west coast, which ecibraccS portions of the states of Chihuanua and Durango.
 What . country hus proddeod in tbe past is of interest only as i'.Gica- ten of what it may do tu the future, and the record of the section Of the country properly tributary to the west coast is cert aIpIy Iuccurasins for the production Ct precious metals IF the future, particularly when il IS considered that the methods used n extracting the !iund eds Of millions known to have been taken from the veins and deposits of this section ! were crude in the extreme, and that
 the science of mining as understood
 by these doing the work permitted i Of nothing but superficial work be- | ing done.
 Rarely Reached Water Level.

 and in but few known instances gone l below, and then only for a few feet. The metaIlurgicaI knowledge of those
 dc1ng this work made possible a say
 in;, of not more than fifty per cent, or the values contained in nearly all the ores mined, and much less in many instances. Modern practice Ipermits of the treatment of ores of q grade too low to be considered by tho miners of a few years ago, and : ope ned a large field for the miner ci
 today. The copper production Of one lone ? camp in Sonora has put that state al the head or the states or the republic for mineral production, and placed the republic of Mexico second in tho list of copper producers. -Cananea i: great copper camp, and will con tinue to produce for a great many
 years to come, but the entire copper and gold wealth of the camp is a: nothing compared to the known cop per deposits of the west coast as ye undeveloped, or only partially deyel
 oped.
 The great copper camps of Arizon; are on the northern end of the tre
 mendous systems of copper belts ex
 tending far to the south of the Amer
 Iican line. After crossing the line tn,
 copper deposits are larger, of slightl,
 better grade than those ot the north
 and carry more gold and silver val '. ues. Just how far to the south thes . large deposits of red metal extend i 2 not definitely determined, as wha : little work has been done along th known belts has developed numbe . of very promising copper showings. n Very little has been done to deveI l. iopo. the copper wealth of the state
 of Sonora and Sinaioa and the west
 ern portions of the states of Ch1nua
 hua and Durango because Of the dii
 ficulties of transportation, but her ! and there properties have been oper r. ed and worked for the goSd and si ? yer values earned in the copper ores l This has been made possible becaus ,, of the existence of small seams O
