1t Is a wonder tnat SO lar no y
great essayist has produced an :
everlasting dissertation on the -,
monotony of man How much n
easier it is to say the same p
thing over and over again or
to ring changes deceiving your
self only, than it is to come out
with something original. a
continued residence in :
Hawaii will reduce the vocabu- l
larry as it limits the range of
comment. This may be alter
ed considerably when we have
a cable and get mail more fire.
quently. How isolated we
really are. There was one
stretch this year of twenty-five ;
or twenty-three days without
a single word from the outside
world. 1t is a marvel the
community does not quarrel
during those fasts. But to
return to and give an instance
of the monotony of man as an
individual. At Paso Robes,
! California, where the principal
yard work of the householder
lis removing acorns from the
lawn and walks, they have
sulphur and mud springs of
great medicinal powers. Just
ike some fellows once describ-
ed the volcano as looking like
hell, a one-lunger at Paso
Robes, in an inspired mo-
ment, remarked as he sat in
. mud bath that he was uncer-
. tain as to whether he had after
: the experience, more or less
. respect for a hog. About 81 of
every 100 persons who visited
f the place since that time have
f repeated this and half of them
. at least have thought they
, were springing something real
clever. Around Paso Robes
f are the greatest prune orchards
of the world, the best soils for
spuds and same of the best
n wheat fields.
