Doubtless the annual crops will in the final analysis prove
the world's greatest and most permanent source of wealth, though at present the waste is even greater than the waste of trees. To compare small things with great, most of us grow in our gardens plants of whose uses we are altogether ignorant or careless. One of the more valuable is a common herbaceous plant, often grown commercially for the sale of the flowers, and especially beloved of florists ; but it has other uses now—the subject of intensive analysis by the chemists. Like the nicotine herbs, it contains an essence that is a deadly insecticide, and it is more than likely that we shall soon Le growing it on a commercial scale for this purpose only. A rough border that pays its way, by supplying insecticides and a useful manure when its beauty is over, is an ideal indeed * * * *
