Under the eoveneey of the Incas, the guano was con- 
fidered as an important object of Dg economy. It 
was prohibited, under pain of death, to deftroy any of the 
birds on the Guano iflands, each of which had its infpec- 
tors, and was divided into departments. From Arica to 
Chancay, a traét of 2co leagues in length, no other manure 
was made = of than guano (Garcilaflo, Hiit. -de “ Pri 
i. p. 184.) This great care accounts in fome meafure for
