He is 50, this author of Time To Live. The home of which he wrote three book has been sold. He and his family have fitted themselves into the miracle house in Chevy Chase, the one place near his job in the Dept. of Agriculture where they would feel at home with earth to call their own and myriads of birds. This book is a medly of autobiography, of tribute to those nearest him, and to his fellow workers; and of the philosophy of fifty years of age, with health, sufficient wealth, and a jot that holds the imagination. The balance of the text is chiefly devoted to that job, to the history briefly of the Department, and to what it means to America today and tomorrow.
