Describe the five rocks Bud always carried with him, since his mothers death.

From the text:

I picked up the tobacco pouch that had my rocks in it and pulled the drawstring open. I shook the five smooth stones out and looked at them.

I reached in and took one of the rocks out. Written on the back of it was "idlewild in 5.2.36." I took another one and it said 'preston in. 6.4.36." These were just like my rocks! I took one more and it said, "chicago in 3.19.32."

"Bud, I know you're not the sharpest knife in the drawer, and I hate to be the bearer of bad tidings, but those are found all over the world. In fact, they're about as common as rocks."
I almost didn't answer him but since I didn't want to look so stupid I said, "Yes, sir, but mine have writing and numbers on them too."

Finally I decided that Mr. C. had waited long enough. I stuck my rocks in his face and said, "See, I told you I had some rocks like those, the only difference is mine say, 'flint in dot eight dot eleven dot eleven' and 'gary in dot six dot thirteen dot twelve."
