“Now _you_ must hunt for worms and flies, You’re getting fat and lazy, For food and drink, your constant cries, Just drive me nearly crazy. “Now I will take you, one by one, And you shall each know how; Red Robbie, you’re my eldest son, Come down upon this bough. “Now hop out on the edge, my dear, Of this your pretty nest, And spread your wings, and fly right here, Just so; now do your best.” “Peep! peep! don’t make us go alone; We are not big enough, Our bodies are not fully grown, Our feathers yet are rough. “_You_ get our food; we can _not_ fly— ’T would hardly keep you busy. Peep! peep! oh! oh! it is so high I’m almost getting dizzy.” “Come, robbie dear (chirp, etc.), come right along, Spread out your little wings; Chirp! Chirp!

By PROF. J. TINGLEY, PH. D. Ten years ago the lamented Agassiz undertook the establishment of a summer school, at the seaside, for the benefit of teachers of natural history. There was first prominently inaugurated the system of summer instruction which has since been successfully practiced at Chautauqua and elsewhere, in other branches of knowledge, and which seems annually to be growing in popular favor. For this reason it has been thought that a brief account of the life and work at Penikese would be welcome to the readers of THE CHAUTAUQUAN. A volume might be written without exhausting all the points of interest connected with the story. The lectures daily delivered for seven weeks to the students there assembled would themselves fill many volumes. Our sketch, therefore, must of necessity be imperfect, affording glimpses only of that time so full of activity, delightful study, novel impressions, and golden promise. As far as possible, it shall be representative, and afford a clear conception in outline of what was designed and accomplished. Prof. Agassiz, being the master spirit—the soul of the enterprise—must be, of course, the central figure in the foreground of our picture. What a delightful summer it was! Undimmed by any presentiment of the shadow which, so soon after, was cast upon its memories, the picture of Penikese, its active life, its cheerful surroundings, its brilliant designs for the future, was a picture of energy, enthusiasm, and hope. The summer was one of bright, unclouded skies, the air laden with
