James Douglas Instrument al in Securing Interesting Display for Educational Feature of Exposition.

Statewide significance has been given the industrial exposition at Phoenix the coming week of Novem Der :, by the announcement that one of the most interesting and magnifi- cent displays of the entire exposition will be that showing the varied uses for Arizona copper.
 This exhibit has been secured by the Builders Exchange, and is made possible by the personal efforts and untiring zeal of MT. James Douglas. it is announced. The exhibit is de- signed to emphasize the growing inn portance of the copper industry Of Arizona, and through demonstration aid in the popular movement Buy Something Made of Copper
 One of the interesting phases Of the exhibit will be an arrangement of samples showing the gradual tram as taken from Arizona copper mines down through various stages of re- finement to the finished products.
 The finished articles will be high ly furnished. and set against a back ground of jet black, making them stand out like pure gold. The effect will be heightened through the use of special electrical illumination at night.
 One division of the exhibit win show the simpler orms Of manufac- tured articles -slIchsas measures. bars. wire rope, -4ls of every size and description from diminutive shingle nails to heavy spikes, all of pure copper.
 In the next division will be shown the modern Spanish roofing tile and Spanish shingles pressed from pure copper. The tiling resembles the or dinary form of red tiling. but when exposed to the elements turns a beau tiful mottled green. Cutters. rain
 spouts. with ornamental brackets
 and flashings are also made of the
 same material
 One division will be devoted to | the display of copper household uten- sils manufactured at Ajo. This cop per manufacturing industry is des-. | tined to be one of the most import ant in the state. Use of copper in l the arts will be exemplified by beau | tifully designed hand hammered cop ! per electric lamps and other electric ! fixtures
 The use of copper for radiators in | the home will also be demonstrated | In this connection 1t will be pointed out that copper has a radiating ca paclty two ana hall times as great as iron. and as a result the copper | radiators may be made much smaller | to obtain the same heating effect | than the iron radiators. The new use of copper for auto | mobile radiators. a discovery which | is destined to reyoIutionize the in | dustry. will be exemplified in a cop | per radiator core for a Cadillac au tomobile. showing how the use of | this metal is much superior in se- curing non-leak radiators at smaller
 expense, than that involved in the
 present process.
 Excellent sample of copper screen ! ing of all sizes will. be shown The
 demand for copper for this use is | growing by all who seek permanency
 in construction Copper screens are 1 the only kind used on Pullman sleep ! CTS One sample will show a heavy | copper wire mesh for elevator guarNs
 and similar uses.
 A number of copper tubes of var1-
 ous sizes and thickness will show the use of copper for steam fitting. cash carriers, and similar transmits
 sion systems.
 Another interesting display will
 be of copper canteens manufactured
 by the Arizona Cornice Works. It | is interesting to note that the New
 York manufacturers who make a speciality of Arizona copper utensils.
 did not know what a canteen was like, hence the demonstration of an
 other manufacturing possibility
