Q: The Hadean () is a geologic eon of the Earth predating the Archean. It began with the formation of the Earth about 4.6 billion years ago and ended, as defined by the ICS, 4 billion years ago. The geologist Preston Cloud coined the term in 1972, originally to label the period before the earliest-known rocks on Earth. W. Brian Harland later coined an almost synonymous term: the "Priscoan period". Other, older texts simply refer to the eon as the Pre-Archean.

"Hadean" (from Hades, the Greek god of the underworld) describes the hellish conditions then prevailing on Earth: the planet had just formed and was still very hot owing to its recent accretion, the abundance of short-lived radioactive elements, and frequent collisions with other Solar System bodies.

Since few geological traces of this eon remain on Earth, there is no official subdivision. However, the Lunar geologic timescale embraces several major divisions relating to the Hadean, so these are sometimes used in an informal sense to refer to the same periods of time on Earth.

The Lunar divisions are:

In 2010, an alternative scale was proposed that includes the addition of the Chaotian and Prenephelean Eons preceding the Hadean, and divides the Hadean into three eras with two periods each. The Paleohadean era consists of the Hephaestean () and the Jacobian periods (). The Mesohadean is divided into the Canadian () and the Procrustean periods (). The Neohadean is divided into the Acastan () and the Promethean periods (). , this has not been adopted by the IUGS.

Q: Valentine's Day was coming. Helen felt hurt and lonely because this was her first Valentine's Day after the divorce .

Helen's twelve-year-old son, Jack, looked at his mother, knowing that this was a difficult time for both of them. In order to make his mother happy, he prepared a present, and handed it to her on Valentine's Day.

It was a beautiful gift package .Helen couldn't believe what was happening. She opened it and took out a lovely card and a small box.

"Now," he said, "read the card." It read as follows:

"I know that this isn't easy for you because it has been a hard year for both of us. I know that Valentine's Day is a special day for people in love. I want you to know that I love you. I know that Valentines are supposed to get chocolate. I went to the store today to buy some for you. Luckily, I got the last piece. I told the clerk it was just perfect."

Helen stood there for a moment and looked at her son. Her eyes sparkled in the light as tears formed in each corner. Jack knew he had done the right thing. Slowly she opened the small box, careful not to tear the paper. She would never forget the moment. She found a chocolate heart that was broken into pieces along with a note:

"I am so sorry that Dad left us, Mom. And all you were left with was a broken heart. But I just want you to know we still have each other.

Happy Valentine's Day!

Your son,

Jack"

Q: CHAPTER VI

THE FUN OF A NIGHT

"My gracious, Plum acts as if he was scared to death," observed Phil, after the bully and his companion had departed, leaving the others a clear field.

"He certainly was worked up," returned Dave. "I wonder what he'll have to say to-morrow?"

There was no answering that question, and the two boys hurried to where they had left Sam without attempting to reach a conclusion. They found their chum watching out anxiously.

"Well?" came from his lips as soon as he saw them.

"It's all right," answered Dave, and told as much as he deemed necessary. "Come, we must hurry, or Job Haskers will get back before we can fix things."

"This ram is going to be something to handle," observed Phil. "No 'meek as a lamb' about him."

"I'll show you how to do the trick," answered the boy from the country, and with a dexterous turn of the horns, threw the ram over on one side. "Now sit on him, until I tie his legs with the straps."

In a few minutes Dave had the animal secured, and the blanket was placed over the ram's head, that he might not make too much noise. Then they hoisted their burden up between them and started toward the Hall.

It was no easy matter to get the ram upstairs and into Job Haskers' room. On the upper landing they were met by Roger and Buster Beggs, who declared the coast clear. Once in the room of the assistant teacher, they cleared out the bottom of the closet and then, releasing the animal from his bonds, thrust him inside and shut and locked the door, leaving the key in the lock.
