and fleshy--something like a short round pointed stick. They grow close
against the stalk, not in pairs, but alternately, first a leaf on one
side of the stalk, then a leaf on the other. They are erect too; that
is, they point in the same direction as the stalk.

On the barren stems the leaves grow so closely that they quite cover the
stalk. They have a hot sharp taste, and the plant is sometimes called
"Wall-Pepper." The roots are very thin and can spread easily through
narrow chinks of the wall.

We will see one more plant of the walls before we look for flowers
elsewhere. Our next plant is not very common at Willow Farm; still I
know where to look for it. Built against one side of the big barn in the
foldyard is a little lean-to shed. Often there are calves in it; but
just now we are more interested in something that is on the roof.

Standing close to the wall of the shed is a cattle crib--a kind of big
square box or trough on legs, in which hay or chaff is put for the
cattle. The shed is not very high, and by standing on the crib we can
scramble on to the roof. Here is the plant we want to see.

It is the Houseleek, of which a clump is growing between the tiles.
Almost flat on the tiles is a dense mass of large green fleshy leaves.
These leaves are evergreen, they do not die and fall off in winter. From
this cluster of leaves rise straight thick stems nearly a foot high. The
stems are thickly covered with erect leaves which grow smaller towards
the top of the stem.

At the top of the stem is a cluster of very handsome rosy-red flowers.
Each blossom is star-shaped when fully open, and generally has twelve
