The plan of this work contemplates a short, timely nature story, or seasonable hint for every calendar day in the year, telling the reader just what time in the successive seasons to look for the different birds, beasts, flowers, etc., how to recognize and study them when taking observation walks for pleasure or instruction. Recognition of different creatures, etc., is assisted by numerous excellent illustrations, and alternate pages are left blank for reader's notes or record of things seen. A yearly report so kept, either by a single young person or a small group or club, cannot fail to be a source of continuous interest, not only while being made but after its completion. A club competing for the best and complete record so made should produce pleasure and instruction throughout the year.
