These her- bicides are poisonous, and must be used with caution and only by those who are reliable and who understand them. 419. Poisonous Plants.—Many plants produce ill effects on live stock and human beings when eaten; and some are in- jurious to the touch. Some plants produce such marked results, leading even to death, that they are known as poison- ous plants. Some of the mush- rooms are examples, two of which are shown in the illustrations (Figs. 419, 420), (wild mush- rooms should never be eaten ex- cept on the advice of someone who knows the different species). Many plants of the parsley family (Umbellifcrae) are poison- ous; the poison hemlock and the water hemlock or mus- quash-root are deadly when eaten. The poison ivy is shown. 424.
