to give up the cultivation of wheat in the northernmost states, 
and our cotton crop could have been perhaps doubled, to say 
nothing of fruits and vegetables. Increased attention is paid now 
in England to economical zoology and botany. A botanist has 
recently been appointed to the Royal Agricultural Society, and an 
entomologist will soon be elected.
