In one kind, the electricity is excited by 56 . EOCK BLASTING. friction, and stored in a condenser to be afterwards discharged by suitable means provided for the pur- pose. In the other kind, the electricity is excited by the motion of an armature before the poles of a magnet. The former kind are called "frictional electric " exploders ; the latter kind are known as "magneto-electric" exploders. When a magneto- electric machine contains an electro-magnet instead of a permanent magnet, it is des...cribed as a "dynamo- electric exploder. Frictional machines act very well as exploders so long as they are kept in a proper state. But as they are injuriously affected by a moist atmosphere, and weaken rapidly with use by reason of the wear- ing away of the rubbers, it is necessary to take care that they be in good electrical condition before using them for firing. Unless this care be taken, the quantity of electricity excited by a given number of revolutions of the plate will be very variable, and vexatious failures will ensue.
