Guano is rightly discarded, or nearly so, from the ' 
list of manures. To it can be attributed much of 
the disappointment of early manuring, and many of 
the desolate fields one sees. It may be serviceable 
at great elevations in small quantities, but it is un-

remark that the freer from weeds a property is, and
