Use Tuffa Rock For Your Rockery 
Much of the charm of a rock-garden 
depends on its setting. A rock garden 
is not primarily a pile of rocks; the rocks 
are employed for the purpose of provid- 
ing proper conditions for the growing of 
plants. And the plants should be such 
that specially thrive in rock crevices and 
pockets. We have a limited supply of 
this unusual type of rock perfectly suit- 
ed for rockeries. This rock is petrified, 
aquatic vegetation, and very porous, SO 
that plants may be planted in the rock it- 
self, where they will thrive well. A rock- 
garden properly placed, constructed, and 
maintained, and with a population of 
well-chosen and skillfully grown plants, 
constitutes one of the choicest depart- 
ments of horticulture. Tuffa rock sold 
by the piece or ton. See our list of rock- 
garden plants beginning on page 28.
