DEFENCE BONDS NEVER FLUCTUATE IN VALUE 210 The man with his savings in Defence Bonds knows that his money is absolutely safe. From the day you invest your first £5, Defence Bonds begin to earn interest at 3% per annum. This interest, which is paid half-yearly, is subject to income tax, but the tax is not deducted at source. Defence Bonds can be bought in multiples of £5 through a Savings Group or War Savings Centre, from your bank or stock- broker, at any Trustee Savings Bank and at most Post Offices.
