Appendix SECTION I TREASURY DEPARTMENT CIRCULAR REGARDING PLANT INTRODUCTION, SEPTEMBER 6, 1827 "The President is desirous of causing to be introduced into the United States all such trees and plants from other countries, not heretofore known in the United States, as may give promise, under proper cultivation, of flourishing and becoming useful, as well as superior varieties of such as are al- ready cultivated here. To this end I have his directions to address myself to you, invoking your aid to give effect to the plan that he has in view. Forest trees useful for timber; grain of any description; fruit trees; vegetables for the table; esculent roots; and, in short, plants of whatever nature, whether useful as food for man or the domestic animals, or for purposes connected with manufactures or any of the useful arts, fall within the scope of the plan proposed. A specification of some of them, to be had in the country where you reside, and believed to fall under one or other of the above heads, is given at the foot of this letter, as samples merely, it not being intended to exclude others, of which you may yourself have knowledge, or be able on inquiry to obtain knowledge. With any that you may have it in your power to send, it will be desirable to send such notices of their cultivation and natu- ral history as may be attainable in the country to which they are indigenous; and the following questions are amongst those that will indicate the particu- lars concerning which information may be sought: 1. The latitude and soil in which the plant most flourishes. 2. What are the seasons of its bloom and maturity, and what the term of its duration? 3. In what manner is it propagated? by roots, seeds, buds, grafts, layers, or how? and how cultivated? and are there any unusual circumstances attending its cultivation? 4. Is it affected by frost, in countries where frost prevails? 5. The native or popular name of the plant, and (where known) its botanical name and character. 6. The elevation of the place of its growth above the level of the sea. 7. Is there in the agricultural literature of the country, any special treatise or dissertation upon its culture? If so, let it be stated. 8. Is there any insect particularly habituated to it? [141]
