§ We propose to re-enact Part I of the Safeguarding of Industries Act, called the Key Industries Duty, which otherwise would lapse this year. These industries are essential factors in the national defence. The principle of safeguarding them has never, since the War, been seriously disputed by any of the three parties in the State. An expert Committee has revised and refined these duties. The modifications are slight, and yield only an additional £50,000 of revenue this year and £60,000 in a full year. Except in the case of optical glass and instruments, where the tax is increased to 50 per cent., and some other small additions to the duties, they are practically the old duties that are re-imposed, but they are re-imposed for a period of 10 years.
