Show Rubber Trees In the United States. The plants which produce the principal princi-pal portion, if not all, of the rubber supply, are natives of tropical America. As there is no similar climate in the United States, it is altogether unlikely that any of these trees could be cultivated culti-vated to be of any commercial importance impor-tance in this country. Although an almost al-most tropical climate prevails in the extreme ex-treme southern portion of Florida, yet occasional low temperature, even in these portions, would be fatal to the permanency of these plants. |
