Four years ago, a convenient handbook on the production and use of various preparations of the chocolate plant was published by our firm. The present work is designed to give, with considerably more detail, some of the interesting facts relative to the early history and cultivation of the chocolate tree, as well as a fuller account of its botany and the chemistry of its products. Since this brochure will doubtless fall into the hands of some who do not have access to the earlier work, we have used with freedom some of the material employed in that; but we hope that these necessary repetitions will increase instead of impair the value of the pages now before the reader.<br><br>We trust that this second treatise may be acceptable to our many friends who gave so warm a welcome to the first.
