The Ministry of Transport has issued detailed instructions regarding the

immobilisation of cars in case of invasion. "The distribution head, magneto or fuel-injection pump," it says, " should be smashed with a hammer, and high-tension leads removed," adding thoughtfully, " If owners are in any doubt as to how to carry out these instructions they should go to the nearest garage at once to find out." They need not do that. I can tell them. Take a hammer or spanner of sufficient weight in the right hand (or if left-handed in the other one), raise it to a height of some eighteen inches above the distributor-head, magneto or fuel-injection pump, and bring it sharply down. Repeat till the state of smash seems up to Goering standards. I waive all copyright in this guide to action. jANUS.
