THE MANSE GARDEN. 131 



of producing : this is the true power which nature 

 has given him, and which he has yet scarcely learned 

 to exert. When an acre of ground sells for fifty 

 pounds, and its depth of soil is only six inches, it is 

 certain that the same portion may be made as well 

 worth a hundred pounds by doubling the depth of its 

 soil ; and one fourth of this profit would be sufficient 

 to cover the expense of the operation. It is said 

 that the man who plants a tree is a benefactor of his 

 species and so he is; but that man is more the 

 benefactor of his species who trenches as much ground 

 as a tree will cover; for the tree dies and the ground 

 is no better than it was ; but that which is trenched 

 has received a benefit which it will not lose till the 

 end of time. 



As to the mode of trenching for the garden, it is 

 perhaps advisable to put all the earth through a search 

 or riddle of which the wires are one inch apart. ,This 

 may appear too expensive, and may not be necessary 

 for those portions which are designed for vegetables 

 of the stronger and coarser "kinds; but such method 

 will ultimately prove the cheapest in regard to all 

 those places which are used for flowers and small 

 t seeds. Stones must be got rid of; and if they remain 

 to be gathered one by one with the hand as often as 

 the ground is dug, it is manifest that instead of dis- 

 posing of a hundred at once, as in using the search, 

 the loss of time by individual liftings will be nearly 

 as a hundred to one. 



The next thing to be considered for the success 

 of vegetable produce is the preparation of manures. 

 The dunghill should be kept in two distinct portions, 

 the one turned over so as to undergo the process of
