THE "YEAR BOOK OF AGRICULTURAL CO-OPERATION."

Kindly allow me to explain what appeared toyour reviewer to be a " strange series of misprints in the English chapter " in the Year-Book of Agricultural Co-operation, 1931. The prices of milk were correctly quoted throughout " for the year," as repeatedly stated. This is the customary form of quotation of contract milk prices, namely, the total value of one gallon per month for the year at a variable monthly price. —KARL WALTER, Secretary, The Horace Plunkett Founda- tion, 10 Doughty Street, London, W.C. 1.
