"... a neat little volume of carefully selected poems which has just been issued by Miss F. Mary Colquhoun, who is already favourably known as the author of "The Master of Rosca," "Glenroysdale' and the "Communion Afternoon."

The pieces have been chosen "not so much because they are favourites of the compiler as because she has found them suited to impart comfort and encouragement to others in our common pilgrimage and warfare of faith" and the book, which is beautifully printed and well bound, deserves a most kindly reception.
