to the shorter terrace above, and near it, on the lower level, is one of
the great pear-trees that have been trained upon the wall, and that,
with others on the keep above, brighten up the grim old building in
spring-time. _Campanula pyramidalis_ has been sown in chinks on the
inner side of the low parapet, and the picture shows how handsomely they
have grown, supported only by the slight nutriment they could find among
the stones. But, like so many of the Bell-flowers, it delights in
growing between the stones of a wall. It should be remembered how well
this fine plant will succeed in such a place, as well as for general
garden use. It is so commonly grown as a pot-plant for autumn indoor
decoration that its other uses would seem to be generally overlooked.
