���A match is not necessary for starting a fire

if a lens is at hand to focus the sun's

To Carry Fire on a Boat Put it into a Inicket with sand or earth in the bottom. Always try to use live coals or embers for this purpose. They will hold for a long time if covered skilfully with damp moss. To Build a Fireplace for a Semi-Permanent Camp

Set a flat stone on edge for the back. The sides are two flat stones about 6 ins. thick. The front is open. Dig a small pit about 6 ins. deep between the stones. This will soon fill with ashes. Don't remove them. They are fine for roasting corn, potatoes, fish, etc. The stones make a curb which adds mui h to the draft of the fire. The side stones get hot. These serve to put the coffee pot on after it is boiled. Boil it seven minutes. Then set it on the hot stone till wanted. If you want to roast corn, strip it down, remove the

��silk, i)ull back the husks and put it

under the edge of one of the stones.

Pull the hot ashes over it. Treat potatoes the same way.

To Bake Fish

Clean them, season, wrap them with corn-husks, wild-grape leaves, or sassa- fras lea\'es, cover with moist clay and bury in the ashes.

Venison and all kinds of meat other than Isacon or cured ham can be kept from ffies by hanging eight to ten feet above the ground in flour sacks.

Using Gates to Lessen Danger from Truck-Trailers

THE rapidly increasing use of motor- trucks as tractors for hauling trail- ers of various kinds has resulted in the development of protective devices to

��Many accidents might have been avoided by the use of this arrangement

��pru\ent the injury of thoughtless pedes- trians who unwittingly run in between a truck and trailer, when endeavoring to cross a street, thinking that they are separately propelled \ehicles running close together. An English safety-g.ite arrangement is here illustrated. The gates arc built on the lazy-tongs principle so that they can close up or extend as the trailer rounds a curve. They are se- curely attached to triangular supporting frames, fastened to the rear end of the truck frame and the front of the trailer, as indicated.

They are constructid in xarious sizes to span the smallest and the largest dis- tance between a truck and a trailer. In some instances tlie\- ha\e taken the plaieof the customar\- danger ll.ig which 16 often unnoticed.— Victor' Pagi5.
