_Poisoned food and poisonous plants._—Food is occasionally poisoned by natives, either by adding strophanthus leaves or other poisons. The eating of such articles may be followed by severe pain, colic, vomiting, diarrhœa or other symptoms. The general line of treatment should consist in giving emetics promptly, washing out the stomach by means of the stomach tube, and administering large quantities of water, milk, or gruel. Distressing symptoms should be treated as they arise; thus, if convulsions occur, large doses of chloral or potassium bromide should be given; if stupor or drowsiness comes on, the patient should be forced to take hot coffee, stimulants, etc., and made to walk about. If collapse supervenes, stimulants should be freely given, the patient wrapped in blankets, and hot bottles applied to the feet. _Poisoning by bad meat, fish, etc._—The symptoms of poisoning by bad meat, etc., are severe pains in the belly, cramps, and shivering fits, followed by vomiting and diarrhœa coming on soon after its consumption, occasionally within an hour or two. The vomiting and diarrhœa are usually alarming and very severe, causing great collapse, and unless urgent remedies are applied, death may occur. The bodies of patients may be covered all over with irritating blotches, red rashes or with nettle rash. _Treatment._—Give an emetic at once. Administer a sharp purge to clear out the bowels. Use stimulants freely. Apply hot-water bottles and blankets. Give opium or chlorodyne, fifteen drops every four hours until the pain is relieved. Milk and gruel or arrowroot. CANOEING AND BOATING. _By J. COLES._ _Canoeing._ _Choice of a Canoe._—In making choice of a canoe the traveller must bear in mind that, in all probability, there will be rapids in the river, which will necessitate a portage being made, and that the canoe may have to be carried over rough ground for a considerable distance. For this reason, it is far better to take two canoes of moderate size than one large one, besides which, a small canoe is much more easily handled in bad water, and even should it become necessary to carry a large load, this can easily be done by lashing two small canoes together, at about one yard apart, and laying a platform across them, on which to place the stores, &c. This, however, should not be done in dangerous and rapid rivers. The following remarks do not, therefore, apply to large canoes, which, having nearly the stability of a boat, may be handled in the same manner. _Paddles._—It will generally be found that the native paddles will be best suited for the work. The double-bladed paddle, such as is used with the Rob Roy canoe, is quite useless on a rapid and dangerous river.
