 children within, and his pig without doors ; and 

 they all grow fat and healthy upon this diet, and

 vegetable; and if the human race continue increas- 

 ing, the cultivation of it may be extended to meet 

 every demand, which no other earthly 'product 

 could scarcely be found to admit of. The increase 

 of mankind throughout Europe, within the last 

 forty years, has been most remarkable, as every 

 census informs us, notwithstanding the havoc and
