We Jiave already seen that it requires about eight 

 thousand one hundred feet of matting to shelter one 

 acre, which, at six dollars and thirty-eight cents the one 

 hundred yards, would give a preliminary expense of 

 one hundred and seventy-two dollars. As these mats 

 will last ten years, the annual expense, per acre, will 

 be seventeen dollars and twenty cents for the mats 

 alone. 



But we must also take into account the building of 

 sheds, in which to store these mats ; and, lastly, the 

 manual labor for placing and removing them. We 

 have already said that the mats necessary for each acre 

 require a shed of fifty-four cubic yards' capacity. This 

 shed will cost about twenty-six dollars, with interest at 

 five per cent. Its duration will be about twenty years, 

 and this gives an annual expenditure of one dollar and 

 thirty cents per acre, each year, for the sheds. 



Supposing these mats to be laid down and removed 

 twice each year, as we have already advised, this will 

 necessitate twenty-four days* labor, at fifty cents, or 

 twelve dollars and sixty cents per acre, including inter- 

 est on capital, at five per cent. 



We must also reckon, in this expenditure, the in-
