If the right of Peru to the guano is to be disputed, let it be done by national vessels and not by armed privateers. If farmers are convinced that we have made true statements of the value of guano in renovating the poor and worn out fields of America, let them purchase at once. The only question to ask is not whether we can go to the Lobos Islands to get guano--nor whether it would be better to buy it of government agents, or speculators on private account, but DOES GUANO PAY? Because, if it does pay, that is, if the farmer can buy guano at present prices, and realise an increase of crops more than enough to pay the expense, it does pay. We think we have shown this fact by incontrovertible evidence. If the first crop pays for the guano and no more, the farmer has a certain profit in the improved condition of the land. If the first crop does not pay, the land will be enough better to pay cost. Upon this point, Mr. Mechi, of England, whose name has become world wide known as an improver of the soil, says; "Whether guano will pay, depends upon the condition of the soil. On poor exhausted soil it is a ready and cheap mode of restoring fertility. I used it extensively when I first began farming, and when applied to the grain crops at the rate of two to three cwt. per acre, it paid well; but now it has lost favor with my bailiff, which is easily accounted for; my land being at present so well filled with manure, nitrogen or ammonia, that we can grow ample crops without it. When the land only yielded two to two and a half quarters of wheat per acre, it was grateful for guano; but now, with a produce of five quarters, there is no necessity for its use. Or rather, the increased supply of farm manure supplies that necessity."
