the mental exercise which he may thus obtain, 

 while labouring in his proper calling. The 

 words of Sir Humphrey Davy in concluding his 

 volume on this subject are admirable: "The 

 same energy of character, the same extent of 

 resources which have always distinguished the 

 people of the British Islands, and made them 

 excel in arms, commerce, letters, and philoso- 

 phy, apply with the happiest effect to the im- 

 provement of the cultivation of the earth. No- 

 thing is impossible to labour, aided by ingenuity. 

 The true objects of the agriculturist are likewise 

 those of the patriot. Men value most what 

 they have gained with effort ; a just confidence 

 in their own powers results from success ; they 

 love their country better, because they have 

 seen it improved by their own talents and in- 

 dustry; and they identify with their interests, 

 the existence of those institutions which have 

 afforded them security, independence, and the 

 multiplied enjoyments of civilized life."
