s to determine the factors that influence the hardiness
of plants.

Strawberry No. 1017, from the Minnesota Fruit-Breeding Farm, made an
excellent showing in 1915, and all plants bore some fruit. Only a few
runners were made, however. All plants were potted in fall, so no data
has been secured on their hardiness. Several hundred more plants of this
variety were set out this spring and they made an excellent stand.

_Syringa Japonica._--The Japanese tree lilac has often been recommended
by this station, but last winter was unusually severe, and an old tree
obtained from Prof. Budd, nearly thirty years ago, now shows several
damaged branches. Younger trees on our grounds and in the city parks
show no injury. Perhaps this tree cannot be expected to live to be much
more than thirty years of age nor attain a much greater height than
thirty feet. The old tree is throwing up new stems from its roots and
may rejuvenate itself.

_Caragana._--The small shrubby caragana (Caragana pygmaea) was unusually
fine this spring when in full bloom. We received it from Prof. Budd many
years ago. It does finely in the clay banks of Lincoln Parkway in this
city, but it is seldom offered by nurserymen. Caragana frutex, formerly
called Caragana frutescens, is a somewhat taller shrub and not quite so
floriferous. It makes a fine screen. Both of these shrubs are addicted
to root sprouting, and might not please those who care for a stiff,
formal garden. Both may be readily propagated from root cuttings.

_Roses._--Hansen's Tetonkeha rose at this writing is in full bloom and
is a very striking object. It grows to the height of about four feet and
needs no protection. The flowers are large and of a deep pink color. It
seems to be as hardy as the old yellow rose of our gardens, that rose
being now, too, at its best. Among other garden roses Paul Neyron is in
a rather weak condition, Ulrich Brunner is doing a little better, while
Mme. Georges Bruant is doing still better. Rosa pratincola grows on our
grounds naturally, and we have brought in from the edges of the timber
Rosa Engelmanni and Rosa Maximilliani. A friend in Duluth has sent us
Rosa Sayi, and we obtained Rosa Macounii from the Bad Lands of North
Dakota. These roses, as well as the more common Rosa blanda, make an
interesting addition to the hardy border.

_Delphinium Formosum._--We obtained a plant or two of the old tall
la
