natural result of low price ; but when the price 

 rises, increased acreage quickly follows. Were 

 the price to rise steadily, and show signs of 

 permanence, the second-crop system would ex- 

 tend, and continue to do so until the increase of 

 produce was found to check the rise in price. 

 Barley may be taken after barley with more 

 success on many soils than wheat ; and where 

 there is reason to suppose that a second crop of 

 wheat, however carefully the ground may have 

 been managed and manured, may be likely 

 to fail, barley may, with great probability, be 

 expected to succeed. 



The use of nitrate of soda or other sources of 

 ammonia, combined with phosphatic manures, 

 promises to be a more permanent resource to 

 British agriculture than Peruvian guano, which 

 unites the same properties in itself, but seems 

 likely soon to become exhausted. Autumn Autumn
