it is especially with the means and objects of ordinary culture of 
fields. To gather, therefore, from a widely-scattered literature 
that, which might be here instructive or suggestive, was mainly 
my task, though those gatherings may prove insignificant. 
Likely also such enumerations, in a very condensed form, will 
promote our communications for rural interchanges, both cis- 
and trans-equatorial, though mainly with the countries of the 
Northern Hemisphere, which predominantly, if not almost 
exclusively, provided all the vegetable substances, which enter 
into the main requisites of our daily life. Lists like the present 
may aid also in naming the plants and their products with 
scientific correctness in establishments of economic horticulture, 
or in technologic or other educational collections. In grouping, 
at the close of this tract, the genera of the plants enumerated, 
according to the products which they yield, facility is afforded 
for tracing out any particular series of plants, about which special 
economic information may be sought, or which may prominently 
engage at any time the attention of the cultivator, the manufac- 
turer, or the artisan.

found westward as far as Japan ; a native also of the warmer 
parts of Australia, as far south as the Darling Biver ; found 
spontaneously in tropical and sub-tropical America, but

recognised in this Acacia the ancient plant. The scented 
flowers are much sought after for perfumery. This bush

Arabic may be obtained from it. 
Achillea Millefolium, L. 
Yarrow or Millfoil. Europe, Northern Asia and North
