often also called Succory, and, as is well known, 
its roots are commonly used as a substitute for 
coffee, sometimes legitimately but more often as 
an unlawful adulterant. The species grows along 
fences and’ highways, coming into bloom about 
midsummer and remaining in blossom until 
frost. 
Tansy. The rich, aromatic smell of the Tansy 
is familiar to everyone who has wandered along 
country lanes in summer. Starting perhaps from 
an old garden where it was planted early in our 
colonial history, the species has found its way in 
waste places along fields and roadsides. The 
small yellow flowers are so massed in heads as to 
become decidedly conspicuous. This leads to the 
visits of many short-tongued insects, although to 
most people there is little temptation to gather 
these blossoms for close inspection by sight or 
smell. Fortunately, children no longer have 
reason to hate the sight of the plant, as they did 
in former times when Tansy tea was commonly 
used as a medicine. ‘ 
Yarrow. The Yarrow is another plant that 
seems to follow civilized man wherever he may 
go. As it grows by our waysides it seems to have 
comparatively little interest for us, but neverthe- 
less it has been associated with human history 
to a remarkable extent. In former times it was 
also largely used as a medicine.
