207 
years two plants have been growing in the herbaceous grounds, 
the white-flowered one above referred to, and the swamp rose- 
allow, Hibiscus Moscheutos. Some years ago seeds were col- 
lected from both of these plants and sown in the nurseries. When 
the plants derived from these seeds came into flower it was found 
that some of those arising from the seeds secured from the white- 
flowered plant had the flowers of a light pink, as described above, 
intermediate in color between the two species. The hybrid char- 
acter of the intermediate form is also apparent in its flowering 
period, which is intermediate between the two species, The first 
to flower is the swamp rose-mallow, the one with the deep pink 
flowers, without a dark eye in the ia followed by the hybrid, 
while the white-flowered form sends out its first blossoms a few 
days later. The new-comer is certainly a desirable plant, and an 
addition to horticulture. 
On the shore to the right, and out of view in the illustration, 
is a mass of the swamp rose-mallow, its bright deep pink flowers 
a conspicuous feature of that part of the shore. Not far from 
it is a colony of the glowing cardinal-flower at home in its 
swampy surroundings. There are many other attractive swamp 
plants to be found here, including the arrow-heads, the cat-tails, 
the pickerel-weed, the wild roses, and sweet pepper-bush, but 
these cannot all be mentioned. Let those interested visit the 
aquatic garden from time to time, for it presents an ever-chang- 
ing aspect, except for the dainty water-lilies which send forth 
their delightful blossoms the summer through, until frosts cut 
them down. Additions are being made from time to time, thus 
increasing the interest of repeated visits. 
n fulfillment of my promise as to the method 
of ae ais old swamp into an aquatic garden 
old stream found its way through this little transverse ey 
broadening out here and there into swampy areas. One of these 
areas is represented by the aquatic garden. A dam was placed 
in 9 little stream near its lower end, and the banks strength- 
d, thus raising the level of the water until it flooded the 
ie in which the swamp abounded, and the other vegeta- 
tion. During the summer the vegetation was kept cut below the
