Tho following IS given In brief "a the
/ theory most generally entertained by
| scientists. with few exceptions. con-
corning tides: II Is assumed that the
moon. acting alone. would not only raise
a wave on the side OF the eartn nearest
| to II by gravltatiOu. but would also draw
| the earth Itself FAR enough out OF its
! course 10 leave behind some OF the water
on the further side which water would
| then be raised relatively 20 the earlh's
surface and constitute the second udil
wave. the sun alone would act similarity.
although its tilc-raisiug effect b. only
about twO-df,he that Of the moon. Now at
new moon. the sun and moon pull tpgeth-
er" and give higher tides than at the hrst
aud tllru quarters. when the sun draws
it's right angles 10 the line Of the moons
attraction, and. at fun moon. when thc
sun is ON the opposite side OF the earth
from the moon, virtually the same eject
Is observed 90 NJ new moon; but the
double tde-raising action Of the sun would
again be supcrimposcd on that or the
moon. and give tides on opposite sides a.
high as those d fortnight before.
The point g. made by "a writer in one
Of the mechanical journals thai the great
est obstacle now encountered In the sue
cessfh operation Of water wheels g..
from am economical aspect. the too often
entire absence Of engineering skill In ut.lZ-
Ing the power and that many water
power would develop greater efficiency
were il properly controlled. ard had the
turbine been selected because Of lis
adaptabinty to the conditions and been
properly set. ON their introduction he
remarks. turbines were used siug!y. bur
now they are used either sineiy or in sets
OF two or three or more. as eHpodient
and IN batteries OF sets. by the use. too.

the expense Of installing has been largely
reduced and FAR greater economy in tEe
Use of water secured. the growing demand
for large units of power has also been
satisfied SO that whereas. . few Years
back "a 5D0-horse-pOwer turbine was al
most unheard Of. turbines Of 5GoJ-h0rse
power are now employed
