and new growth soon appeared but did not come the next 
year. 
23. Spiraea salicifolia. MEADOW SWEET. A good sized 
piece of this was introduced in early spring, not in the bed 
but along the front of the porch. In its natural condition the 
little thickets of the plant seem quite pretty, but as a shrub it 
was not a success, due to the short life of the branches which 
gave it a ragged appearance most of the time. It was dug 
out after two or three years. 
24. Rosa blanda. SMOOTH WILD ROSE. Whatever may be 
its proper name this is our common woodland rose of the 
eastern part of the state. It is tall and has practically no 
prickles on the upper branches although the new shoots from 
the roots are well covered with them. Two plants were trans- 
planted in early spring to the front side of the porch. In 
spite of an attempt to dig them carefully the large roots 
came up with few branches and no dirt. The first year the 
bushes made very little growth, but did much better the sec- 
ond season. One of them has become entirely too tall, being 
now about seven feet high. _Two new shoots from the roots 
have reached a height of seven feet the past summer. The 
bushes have not shown much inclination to spread from the 
roots until the past summer when new stems came up a yard 
or more from the original plants. The leaves have been in- 
fested badly with leaf miners, and this has detracted from 
the appearence of the plants. 
Il. PLANTS UNINTENTIONALLY INTRODUCED. 
25. Agropyron smithii. WESTERN WHEATGRASS. This 
was in the Szeversia sods. The grass much resembles quack 
grass but is not so persistent in fields, although it often 
causes trouble among groves of trees. In the flower bed it 
began to spread to a considerable extent. The second attempt 
at removing it seemed to be successful, but it also may have 
been responsible for the decline of Sieversia and igi peda- 
tifida. 
26. Agropyron richardsoni. BEARDED WHEATGRASS. A 
plant or two came in the same way as the preceding species.
