<br />shown on the map. Many of them have but n single 10-foot hole on them, and the strike and continuity
<br />of most of the veins or dykes was arrived art largely from the bits of float which were found on top of the
<br />ground, presumably above or near their apexes.
<br />DEVEI.OPNIENTS.
<br />The old developments ou these two groups were neither extensive nor well planned; there are a
<br />few trenches and shallow holes in the wash; there is one 100-toot shaft on the Alta bIont, located on the
<br />hard carbonate basalt dyke. There are three old shafts on~the Deadwood, 50, 60 and 80 feet deep
<br />respectively. (None of these shafts show any ore; and two of them do not appear to have even n vein.)
<br />From the bottom of the 80-foot shaft there is a cross-cat 100 feet long, but the shaft was filled with
<br />water above the cross-cut preventing its exploration.
<br />The shaft being ennk on the Deadwood `'o. 3 is now down 100 feet, and sho+vs a strong phonolite
<br />dyke some ten feet wide, which is spoken of later. This letter development is well planned, and is being
<br />energetically prosecuted.
<br />GENERAL CONDITIONS.
<br />The conditions and facilities for mining and ore redaction iu Cripple Creek are so well known as
<br />to require little discussion. Two railroads already serve the camp, nud another is being built. The
<br />cost of freight is so low that the mines find that it pays better to freight their ores to custom mills and
<br />smelters on the plains rather than to operate reduction work of their own.
<br />Supplies, machinery and fuel are all cheap,. and skilled labor is abnudant. The climate is dry,
<br />cool and wholesome, and oat-door work is prosecuted practically the yens round. There has been a glut
<br />of late iu the ore market, but}conditions cue already improving, and we Wray fool: for greater improve-
<br />ment in the future; for the capacity fot• handling ores in Colorado is constantly being increased. Be-
<br />sides a oonsiderable enlargement of the smelting capacity of the State which is now under way, there
<br />are mills enlarging curd building which will increase the present milling capacity by 980 toes per day,
<br />as follows: The Economic mill, 300 tons capacity, bas started, but is not in +vorking order as yet.
<br />The IIniou Gokl Extrnctimt Co, 2~i0 trots; expect to start the first of August.
<br />The National Gold Extraction Co, are acldint; 110 tons capacity to their present plant, and will
<br />start the addition April 1st; turd other plants atro making additions aggregating 320 tons.
<br />~IEINS.
<br />In studying the veins of thoso groups +ve will consider not only the veins which Lave been proved
<br />to Dross the properties, but also three or four of the strong veins of the cramp which trend toward the
<br />groups, and which. have been profitably worked comparatively Went by these groups.
<br />Of the veins and dykes which may be traced ou the gronnd, I consider the basalt dykes, marked
<br />Josie B. dyke " on the map, mnong the most important. This dyke is very strong and pereietent. Its
<br />structure is compact, and its color greenish art the southern end, but as it goes north its color
<br />changes to a brown, and its structure becomes more "gnartzy," both of which are good indications.
<br />It hue not been opened up after it crosses into Sarah Bell territory, and I should not be surprised were
<br />a good ore chuteto be opened on it a few hundred feet north of its last exposure.
