From careful investigation If the quali,ics
IL coal found in this region, and from tie
best and most reliable information from those
who are using large quantities Of this kind

Il matters but little, 50 far as faets in rela

specific gravity Of water, whether IL be
wasted Or used In is most saving and frugal
manner. This rule will also apply 10 any
other power II must DC confessed. thar
the water power in Moline has hitherto
essp neglected. Wcnow have the improve

another season we expect to have one u the
dnest water powers in the Western world. I.
