Tussy-mussies 301 
Thyme-covered Graves, 
The sense of smell in its psychological relations 
is most subtle : — 
“ The subtle power in perfume found. 
Nor priest nor sibyl vainly learned ; 
On Grecian shrine or Aztec mound 
No censer idly burned. 
“ And Nature holds in wood and field 
Her thousand sunlit censers still ; 
To spells of flower and shrub we yield 
Against or with our will. ,, 
Dr. Holmes notes that memory, imagination, 
sentiment, are most readily touched through the 
sense of smell. He tells of the associations borne 
to him by the scent of Marigold, of Life-everlasting, 
of an herb closet.
