Great care must be taken to make the plug ‘gas fig-ht, so that there shall be no escape of charge or indrawing .oi air through it. and the core must be protected from direct contact with the metal oi’ the shell by the packing gaskets, or else cracking will result. The location of the plug in the cylinder is a matter of considerable importance. Neces sarily, it is always inserted into the cylinder space above the high- est point reached by the piston and it may be located in the cylind- er-head proper, in one of the caps that covers a valve (usually the in- , let-valve) or in the side wall of the cylinder. lt shoud be so placed as not to be unnecessarily eXDOsed to oil or to highly heated burned gas- es and so as to be in touch with the new charge as it enters the cylinder.

BATTERV CHARGING FROM EXTERNAL SOURCES. Private Recharging Facilities are , Advantagcous. A buttery may become (iiscliarg- ed, in service. because the demands upon it have been unreasonably great; ‘because it has been dis- charging through a short-circuit or accidental load or because its gen- erator has not been charging it sufficiently. When this happens, it will generally be found prefer- -able to recharge from some out- side source of current rather than from the generator on the car and in the home garage. The advan- tage of the latter method is the re- duction in loss oi use of the car .as the operation can be conducted dur- ing the idle periods, llfl at night. .1: there is anything wrong with the battery itself, home recharging had better not be attempted. The ap- paratus needed is a source of cur- rent, means-for connecting it to the battery, a, low reading ainiucter and a battery liydronieter. The current must be continuous or dir- ect, flowing in one direction con- siantly and must not Ibe of the al- ternating variety.‘ Coinparativeiy few motorists have access to direct current lighting or power circuits. but such as do have only to cut down the voltage of the supply to the required value, by resistance in the form of incandescent lamps, connected i multiple. The aver» age motorist has alternating cur- rent for lighting in his garage and must obtain some means for chang- ing the comparatively high alter- nating voltago inito a low. direct voltage. A retilier or small alter- nating current motor driving a low voltage, direct current generator is the apparatus required. Rectifiers are upon the market in consider- able variety and such instruments usually embody an sin-meter and i means ‘for connection to a lamp- soeket.
