Abstract
THIRTY years ago planters were inclined, when an outbreak of disease occurred among their crops, to conceal it from general knowledge or observation as much as possible, the result being that little or nothing was known, from a scientific point of view, of the diseases attacking tea. As time has gone on, however, this has altered. Watt and Mann, in 1903, described about a dozen diseases, and in the present volume the number has increased to about sixty. Whether more harm is now being done by disease, however, is very doubtful; on the whole it is perhaps less.
