Behavior of the Earth There arc several factors, some of whi'h are L1nknown, that produce differences in weather. ·One of these is tht earth itself. its movements, ~·hape, and form. and its mountains. valleys, .:nd oceans. The earth has two important movements. It i urns on its axis once every twenty-four hours. This movement causes day and nighr. It is .called rotation. The other movement called f('Volution refers co the earth's travel around the ~un. It takes the earth about three hundred <;ixty-five days ro complete one revolution. The earth as it travels in its pathway through rhc sky does not stay in the same pmition with rrlarion to the sun at all times. At certain times during the year. its position is such that Lhe sun would be directly over its middle. This is true on about the twenty-first of March and twenty-first of September. At this time days .:::nd nights arc of equal length. After March twenty-first. the earth changes iLs position a little each day. The south pole tips f.7'rther and farther away from the sun while the north pole tips toward it. This movement Ant Ways Ants are experts in care of the baby. The ant nurses know exactly how co feed and cake care oi the baby ants in their various stages-as grub or larva. as pupa. and as a real baby ant. When the grub is ready co sleep. the nurses rnver it With earth which serves as a bed. The grub then weaves a silken cocoon around itself. \\'hen the co:oon is finished and the pupa is aln:ady asleep, thr nurses very carefully remove the ccvering of earth. · When the sleeping period is over and the b"by ant is ready to come out. it does not have io bit~ its way out. The nurses know exactly when the pupa should wake up. The attendant W(lrkers are called upon to rip the cocoon on one side and tenderly help the occupants to escape. These little baby ants are pale and weak o.nd their skin is very soft. They are called ca{!ows. While the rnl/ouJs arc hardening their ::;kin. they are fed and cleaned by the nurses. At first only wingless workers are produced. of che earth goes on until the twenty-first of June, when .in opposite movement starts. In J unc the sun seems to be farther north. The days are. in this part of the yea.r, longer than the nights in the northern hemisphere.

He bought a bottle of ink for four crntavos. Jose He gave away his pieces of clean panight to find food. Sometimes all it needs to do is to stretch its head end of the hole and eat what it finds within reach. At other times it has to leave its hole to seek food. The earthworm eats leaves both fresh and partly decayed. For meat. ic eats broken parts of insects. There are many interesting things about the earthworm. It caii. crawl backward as well as forward. It is earless, eyeless, and footless, but it can do many wonderful feats. More About the Behavior of the Earth (Continued from pa.ge 24) sun. The southern hemisphere in turn will have longer days than nights. The Philippines is not far from the equator. Ht.'nce we are near the sun throughout the year i'nd weather is warm all through the year. On which side of the equator is our country loca~ed? Oceans and high mountains influence the weather of a place. Water absorbs heat from the sun and stores it up. In the cold season when the land should be very cold the near-by sea gives off the heat it has stored up and makes the land warmer than it would be if it were far from the sea. In the hot season, the air over the land is cooled by the air from the sea. Thus lhe land near the sea does not become extremely cold or unbearably hot. Mountains affect cli,mate 'by cutting off coo}: iQg winds from large areas. Thi·._:Wind from the sea contains moisture. When it' bldws ,toward the interior, it strikes against the ~Oun t.ains and the moisture falls as rain. When C·he wind reaches the place beyond the mountains, it ic; already dry. Because of such conditions, desi:rts exist beyond high mountains. Baguio which is located among high moun, tains is much cooler than Manila. It is because the air grows thinner as we go upward from sea level. Air holds heat. The thinner the air. tbe less heat it holds. Hence the differ.ence be..! lween the climate on the top of the mountain and that on the valley only a few miles away. -------------·----per. He wanted candies better than books.
