WHEN I WROTE my (well deserved) puff for UNICEF (UN

Children's Fund) Christmas cards the other week I said that `the sale of one box of ten cards means, for example, that fifty children can have milk every day for a week.' A box of ten cards costs 7s. 6d. and a few readers have written to question the calculation. One of them says in parenthesis, 'one teaspoon- ful?' Not at all : one glass per child per day for a week. The milk is dried; it comes cheaply in bulk from various countries; and the cost per glass (mainly transport) works out at a fifth of a penny.
