the prospect for its stock. Some of these anonymous writers assured me that they had sold the stock short at the prices then ruling.
 Helvetia directors have called ar assessment of s1 per share on the companys outstanding stock. The di, rectors visited the property about a week ago and after an examination de cided to make the assessment S1 per share, instead of 50 cents per share as had been previously planned. This is quite conclusive evidence that the directors were very favorably impress ed with the showing made by the re cent development work and are sat isfied that the expenditure of money is warranted. I have reason to be- lieve that the directors of the Hel. vetia company who voted to call this
 assessment are themselves owners of between one-half and three-quarters
 of the company's total capital stock. As the assessment will fall most heav- l fly on them, their action is strong bull point on the company's stock. Greene Consolidated is about to in i troduce the caving system of mining | in two or three of it's producing mines. This system is used in all of the larg.
 CT mines in the Bingham camp,and
 also in the iron mines in Michigan. A | familiarity with comparative mining
 costs under many different conditions | and methods makes me confident that
 the caving system in the Greene com pany's largest mines will reduce op erating costs more than si per ton
 of ore, and thus make a saving of fully
 l 1-2 cents per pound of copper pro | duced. At other mines steam shovels will supersede old-fashioned mining
 practices, making a still greater rela-
 tive reduction in average costs.
 The Greene management has inaug-
 urated a vigorous and comprehensive l campaign of cost reductions. In ad | dition to mining all it's ores at a much | smaller expense than heretofore. it | is increasing the capacity and effcien-
 cy of it's concentrating mills and smelt- I ing plant. The new reverberatories
 will greatly cut down the cost of hand | ling fine ores, concentrates and flue
 dust, and the roasters will make avail
 able an emmense tonnage of compara. l lively high grade ore which can not be
 treated at present because of an exces-
 sive percentage of sulphur. Taken
 all togther, the reforms, improve. I l should reduce the cost of Greene's
 output at least cents, and perhaps
 3 cents, per pound. At the same time
 these extensions will provide for .
 rapid increase in the volume of it's | production, from around 65,000, 900 pounds at present to 100000, 900 l pounds annually few years hence. | The Greene management has been
 developing new system of concen tration which promises to add mate rially to net earnings. The basis of the system is chemical affinity. Ger tain chemicals are combined with De | troleum residue and rosin and then 1 mixed thoroughly with finely crushed
 ore The mineral adheres to the 1 chemicals and floats on the surface of l the water, where it is collected. This process has been tested quite exhaust lively on sample lots of ore from a
 large body, found in one of the Greene l mines, which does not yield it's values l to the ordinary concentration process,
 and the surprising result of 97 1-2 per
 cent recovery has been attained. The
 new system is so inexpensive that it is possible that million or more tons
 of tailings accumulated below tho
 company's mills may be treated at a
 substantial profit. A mill will proba
 bly be erected in which all the compa- l ny's low grade ores which do not con
 centTate well will be treated by this
 new process.
 | understand that an effort was
 made some time ago by certain specu lative interests in New York, who
 have made very successful turns in other stocks, to secure calls on large
 lots of Greene Consolidated preparato-
 ry to a bull campaign in the stock.
 They were unsuccessful. being told by the insiders that they did not have
