Puzzle 13

It's time for a puzzle submitted by a reader of this site. This comes from Matthew Daly (thanks!)

A word of caution, I haven't tested these myself - it's the lack of time thing. I'm sure Matthew will keep an eye on comments.

Next week I'll post Matthew's Solution.

Over to Matthew:

I'm awfully sorry, because I've been enjoying your site for some time now and ignoring your invitation to give something back in the form of our own puzzles.

2b) otrnwdoueoerntnasewhtnthr

I took two of my favorite riddles and encrypted them, breaking the longer one in half. I used the same transposition scheme for all three pieces, so you may wish to take twenty-five strips of paper and write the n'th letter of each piece on a strip and then rearrange them to reform the riddles. Perhaps you may also find the relationship between the answer to the riddles and the encryption technique.

For people who need a little guidance, here is a hint in a much more familiar cipher:

D NQRZQ SODLQWHAW DWWDFN ZRXOG EH IUXLWIXO,
KRSLQJ WR ILQG FRPPRQ ZRUGV LQ WKH ULGGOHV.
IRU LQVWDQFH, RQH RI WKH SLHFHV FRQWDLQV
WKH ZRUG 'BRX', 'DQG' LV LQ D GLIIHUHQW
RQH, DQG WKH RWKHU KDV 'GRHV'.

As usual, a solution will appear on one week.
