The most remarkable fact concerning this species is the peculiar manner in which it stores acorns. The thick bark of large sugar and other pines has been seen completely riddled with small holes. A section of a partly decayed oak limb, three feet two inches long and five and one-half inches in diameter, contained 255 holes. Each hole is intended to hold a single acorn. The acorns fit quite accurately, are driven in point foremost, and are not readily extracted. Sweet acorns are selected. To get at their contents the acorns are carried to a convenient tree where a limb has been broken off, driven into a suitable crevice, split open, and the outer hull removed. Truly the California Woodpecker is no idler or bungler, nor is he a free-booter, like the noisy, roystering Jay. He makes an honest living, and provides for the evil day which comes alike to man and beast. THE PIEDBILL GREBE. Boys and Girls: This is the first time I've been on land for several weeks. I am sure you can't think of any other kind of bird who can say that. Sometimes I don't go on land for months, but stay in the water all of the time--eat and sleep there, floating around. My little chick wanted me to go on land so we could have our pictures taken. If he were not sitting so close to me you could see better what paddles I have for feet. I build my nest of weeds, grass, sticks, and anything I can find floating around. I most always fasten it to some reeds or tall grass that grow up out of the water. In this I lay the eggs and just as soon as the chicks come out of the shell they can swim. Of course they can't swim as well as I and they soon get tired. Do you know how I rest them? Well, it's very funny, but I just help them up on my back and there they rest while I swim around and get them food. When they get rested they slide off into the water. Are you wondering if I can fly? Well, I can fly a little but not very well. I can get along very fast swimming, and as I do not go on land often, why should I care to fly. Should any one try to harm me I can dive, and swim under water out of reach. Well, chick, let us go back to our home in the water. [Illustration: From col. F. M. Woodruff.
