Pick of the paperbacks; James Herriot's Yorkshire, by James Herriot, photographs by Derry Brabbs. New York: St. Martin's Press. $9.95.

This book gives us Yorkshire in all its spaciousness and generosity, its openness and mystery, its wild bleakness and its fervent challenge. Herriot, a country veterinarian for 30 years, has written enchanting books which have sold millions of copies. His readers, knowing he had traveled these roads, gone up these hills and down these dales, and crossed these rivers till he knew them perhaps better than his children, wanted him to share his land with them. Hence this book.

It's a lovely book; its gentleness has a special animation. To those who already love the wild uplands and lonely moors and broad dales, it speaks with no delay.
