many places in the United States also, where its presence has not yet been dis- 
covered. ; 
Guano is limited in supply, and moreover the opinion is gaining ground in 
Europe that it is exhaustive to the soil, whereas apatite is enriching and sus- 
taining.- A number of experiments have recently been made with this fertilizer 
in England, with most satisfactory results. One of these trials was made by 
Sir Harry Verney. The soil on which he applied the phosphate was a heavy 
sandy loam, resting on a clayey subsoil. The ground was sown with chevalier 
barley with the following result :

These trials entirely accord with the experience of others on the native phos- 
phate of lime, and show that, while in every instance a considerable increase of 
crop was obtained by the addition of certain fertilizers, the Spanish phosphate, 
especially when its action was quickened by the addition of sulphuric acid, 
proved nearly as efficacious as bones themselves, unless, indeed, when the latter 
was very finely powdered. 
STATISTICS OF BAVARIA. 
From figures published by Dr. F. B. W. von Hermann, of the Royal Bureau 
of Statistics, we gather the average yield of breadstuffs and hay per acre in the
