Russian Mining Outlook.—With regard to the conditions
necessary for the development of the Dorietz industry, a
supply of capital is essential. For the minimum necessary
development of the area, such supply must be large. At
present, for the installation of new concerns and new shafts
at the mines now working, for every 10,000 poods of coal
produced in the year it is necessary to spend 4A to 5 million
roubles. Previous to the war, the corresponding figures
were 2^ to 3 million roubles. During the next five years
the increased production must be made to reach a minimum
of one milliard of poods per annum, although only to take
the place of foreign coal, and for the normal increase in
consumption : thus for the fulfilment of this modest require-
ment we should require not less than 460 to 500 million
roubles. Such an increased production is the more neces-
sary, as the industrial concerns of Petrograd and the north-
western shore will naturally be transferred to the Donetz
basin. Meantime, the political, financial, economic, and
social circumstances of the present time give no ground to
expect such a contribution of foreign capital. But as
regards Russian capital, it will probably be directed to the
lighter branches of industry ; for example, textiles, chemi-
cals, etc. Thus it is exceedingly difficult to hope that the
existing concerns will develop : much less then that new
ones will be opened.



CEMENTATION

You Expect to Encounter Water,

You have Feeders of Water,

Pumps are Required,

Pumping Entails useless Cost,
Water exists in SHAFTS or LEVELS,
It would be beneficial to stop such water,
