just few feet underground, in time
to work their way gradually to the
surface.
The action of freezing Is what
brings them up, alternate freezing
and thawing, thus giving a sort of
crawling motion to the very crust of
the earth itself.
This is Natures way Of refining
soil.
1t is probable that the intense cold
of the past Winter has resulted in
many of these arrowheads being
brought closer to the surface. The
one of which we write was found in
yard not so many blocks from old
Fort Stevens.
Washington has had an unusual
history.
For many years 1t was nothing
but a big village, a city in name, but
scarcely that in actuality. This had
its good points as well as its bad
ones.
AS far as the soil is concerned, a
great deal of it still is unworked. in
the true sense 1t has been dug over
a bit, perhaps recently in building
operations, but there remain vast
stretches of ground otherwise un-
touched.
There still are vacant lots in the
very heart of Washington which are
overgrown with weeds. The imagina-
tive beholder we'll can image they
looked in Powhatan's day just as
they do now, although then they were

It is always well. in digging in a
yard. to examine stones that are
thrown up.
Not many of them will be Indian
relics, of course. but some of them
will be interesting bits of rock, well
worth saving. If one is an amateur
aquarist, in particular, some OF these
small rock pieces can be used in
tanks. A good bit Of stone. If well

Stones from the size of the fist to
that of the head have many uses in
gardens. They are used to outline
borders, and beds, and sometimes
play part in the so-called rock gar
den There is a great deal OF mlsap-
prehension about rock gardens {;
many persons think that all one has
to do is place small boulders on the
ground and call the result rock
garden, but such placements, with
plants growing between them, do not
constitute q true rock garden, IN any
/ sense The real rock garden Is slice

| where plants naturally grow in and
among rocks. 1t must have a vertical
plane as we'll as a horizontal. The
/ real rock garden has.
Some local yards continually send
stones to the surface, over the years,
these coming up and finally showing
above the grass. 1t is better to re-
move these, because grass cannot
grow over them very well. Stones
/ thus dug up should not be thrown
away, because the chances are that
a use will be found for them, If not
/ this year, then the next, even if they
wear no such romantic form as that
/ of the Indian arrowhead.
