Adventures of Huckleberry Finn: he whale(s) on me?

I've just decided to write something in English everyday or at least every weekend, in order to improve my writing skills. I am reading the Adventures of Huckleberry Finn and it's a very long story compared to The Man who would be King that I read sometime ago. But the problem I have with Twain's book is concerning the speech and improper grammar used by the characters which sometimes leaves me confused. Huck and the slave Jim are always using strange words and improper English. I must to be careful with these words and speech while trying to build my vocabulary.
Yesterday I found a verb used by the author that I can't find a meaning for. Huckleberry said of his father: "He used to always whale me when he as sober and could get his hand on me". So, I looked for this word in two dictionaries, but I couldn't find a reasonably meaning. What does he mean by "he whale me"?

Someone taught me:
To whale on something is to beat or whip severely, and Huck should say He whales on me.

What do you think? The Adventures of Huckleberry Finn is proper to foreign students?

Why do you obey the rules?

In Brazil, I think the laws are very strict, although people are always complaining about them, and arguing that they are very lax. For example, talking about driving accidents, there are many fatal accidents here (in Brazil), but they are more caused by imprudence and negligence than the absence of laws or lenient ones. In my opinion just the fact that you are afraid to go to jail or have a fine is not an essential condition to make you obey the rules. The effectiveness of the law is much more than its punishment nature, it is concerned about education and the way people internalize the principles, rules and regulations as their own.

My experience with volcano eruption - Cape Verde

In 1995, I was finishing High School, when the Fogo volcano erupted on Cape Verde Island. Well, I wasn't on Fogo Island when the eruption began, I was living in Praia, my hometown and the capital of Cape Verde in Santiago Island, which is neighbors Fogo.

It was remarkable because the eruption started after twenty years of inactivity and everybody had believed that that the volcano was extinct. Fortunately, rescue workers and the military did a great job, and nobody was killed. International aids and donations also came in time, and people were evacuated from their homes to temporary accommodations buildings constructed for that purpose.

In Santiago Island we could see the huge smoke that was expelled out from the volcano, and everything we watched on TV was amazing, even though we were all terrified by the phenomenon. The air was very thick and from time to time we could feel the ground trembling, just a small earthquake, but enough to make all of us pray to God for our lives. Last year, this experience cross my mind again, when I heard that another eruption had began, and they said it is stronger than the eruption that occurred in 1995.
