194 Annual Report of the Consulting Chemist. 
At present most of the cargoes are shipped from the following 
deposits in the south of Peru : Pabillon de Pica, Independencia, 
and the Lobos Islands. 
As far as I have been able to gather information, the Pabillon 
de Pica guano now imported into England consists of three 
varieties, namely : — 
1. Pabillon Guano. 
2. Huanillos Guano. 
3. Punta de Lobas Guano. 
The Pabillon de Pica deposits are dry, powdery, and fine 
guanos, and, as regards condition, greatly superior to Guanape 
and Macabi guanos. 
The most valuable of the three varieties of Pabillon de Pica 
guano is that of Pabillon proper. Of a number of analyses 
of guano from South Peru, I quote only a few, with a view of 
giving a fair representation of the several qualities of some 
of the deposits, cargoes of which have been already shipped to 
England.

Many of the samples of Pabillon guano analysed by me 
contained fully 10 per cent, of ammonia and 25 to 28 per cent, 
of phosphate of lime, and, without exception, all were dry and 
in a fine condition.
