products of the soil, as well as the modes of its cultivation, 

 conspire to affect and control the agriculture of every country. 



Anions; such, climate exercises a paramount influence. Every 

 climate seems to have a particular species f)f vegetation adapted 

 to it : thus the Grains and Grasses of temperate climates are 

 unsuited to equatorial regions ; and the Spices and Fruits of the 

 tropics to the Temperate Zone, the Rice and Cotton of the 

 South, the Hemp and Flax of the North, cannot well be made to 

 exchange places. Art can, it is true to some extent, overcome 

 obstacles presented by nature. With us the Grape and Fig are 

 produced in the highest state of perfection ; and in summer, our 

 gardens are ornamented with exotics, glowing with the rich colors 

 of a warmer region. But this is only done to a limited extent by 

 the creation of an artificial climate in order to gratify the taste, 

 or minister to the wants of luxury. Plants which are indigenous to 

 one country, may be perfectly adapted to another remote from it ; 

 but it must be under the circumstances of a similar chmate and 

 situation ; thus plants and shrubs from the mountain ranges of 

 India, the Himalayas, find a congenial home in the gardens 

 of Europe and America, and flowers from Northern China, 

 flourish and thrive in spite of the rigors of a New England 

 winter ; and even become not unfrequently so perfectly naturalized 

 as not to be distinguished from the natives of the soil ; of this 

 the ox-eyed daisy, or white weed, now scattered over the 

 meadows anl fields of all the fc^astern and Northern parts of the 

 United States, and the wood-wax, confined still to the hills and 

 pastures ol lOssex County, both of foreign oiigin, unfortunately 

 for farmers furnish undeniable evidence. 



Climate not only controls the products of the soil, but 

 materially influences the character of its cultivation. In 

 countries where nature produces spontaneously, or without 

 requiring the aid of human skill and labor, most that his 

 subsistence actually needs, man yields to the enervating influences 

 of climate. AVhere the bread-fruit grows wild, man will not 

 labor to raise corn, for human exertion grows sluggish when the 

 s'lur of necessilv ceases to stimulate.
