Bees are seen on blossoms and carrying nectar and pollen to the nest. Then fol- lows a detailed study of the worker bee including microscopic shots. The drone is seen and also the queen. We see the workers feeding the queen and cleaning her. They also clean out the cells. The queen lays an egg. After three days, the eggs hatch into larvae. Workers feed them. After six days, the larva spins a cocoon. The larva sheds its skin and changes into a pupa. Finally adult bees start to gnaw their way out of the cocoons and the cells. Now they are ready to do their work in the nest. They feed the larvae, ventilate the nest and becom- ing guards of the nest, put to route an intruder bumblebee. When the nest becomes full of eggs and larvae, the workers get ready to raise a new queen. They select a female larva, tear apart her cell and enlarge it. They feed the queen larva royaJ jelly only. They seal the queen's cell. Now the old queen and the field bees prepare to swarm. The new queen pushes aside the cap over her cell and emerges as a full grown queen. The new queen finds another queen cell in the nest. This she tears apart. Another adult queen bee hatches from its cell. The two queens meet and fight a life and death struggle. Workers watch the battle. The field bees which left the nest with the old queen, settle temporarily on a branch. The nest bees stay with the new queen. Scout bees leave the swarm and look for a place to build a new nest. The swarm makes a bee line toward its new home. After the swarm settles the work- ers start to build a new comb. We see workers making wax, secreting it, apply- ing it and shaping it into cells. Bees on flowers gathering food for the new nest. This is shown also through a magnifying glass. The bee returns to the nest and performs the honey dance. When bees visit flowers they get the powder-like pollen on the hairs of the body. With the combs on its legs, the bee brushes the pollen from its body into the pollen basket on each hind leg. The bee actually packs the pollen into these sacs until they bulge. The bee carries the pollen to the nest in these baskets. Back in the nest, the work- er dances around, doing a pollen jig, be- fore she deposits the pollen in a cell. Extra food is stored in the comb for the bees that will live through the cold winter season. Bees are seen in a fleld of clover Film may be used in nature study and elementary science, in general science and agriculture, in biology and entomology and in home economics and vocations Jh-sh-c-aduit Guide 597.8 Toads.

Laurence Palmer, of Cornell university. Presents the life story of an interesting reptile in its natural habitat. Unusual photographic studies permit observation of the snapping turtle's detailed features, habits, and its encounters with other ani- mal life. The laying of the eggs and the hatching are two outstanding episodes. A painted turtle is introduced for purposes of comparison. The winter hibernation concludes the presentation "An excellent film for a wide range of applications; should be especially valuable in biology, zoology, and nature study classes, at all grade levels. The film is well organized; photography and sound are good." Educational screen el-Jh-sh Guide 15c 598.2 Birds Bald eagle.
