SEQUENCING #1:

A New Kind of Logic Puzzle

This month we have a new type of logic puzzle we'd like to try. We call it the Sequencer because it is based on the type of logic used to solve how DNA molecules are made up. DNA molecules are so big they are hard to figure out unless they are broken down first. Enzymes break the DNA into smaller sequences which can be identified by chemists. By using a number of different enzymes that only break molecules at specific places, and counting and identifying the smaller pieces each produces, scientists can figure out how the DNA molecule would have to be put back together, and thus what it's makeup is.

In our case instead of a DNA molecule we'll be piecing together a short cryptogram that Fishy cut up with an axe. You'll have to use logic to put the cryptogram back together. Then you'll have to solve it.

Shotgun Henny's Favorite Saying

Fishy's 80-year-old Friend Henny O'Hara is called "Shotgun" by her friends because she always carries a sawed-off twelve-gauge. According to her, a girl has to protect her honor.

Fishy turned Henny's favorite saying into a cryptogram. In the cryptogram Fishy made, the 6th character represents a space throughout the entire cryptogram, and the 30th character represents an apostrophe ( ') throughout the puzzle.

Fishy carved the cryptogram on a hand-hewn pine board. When he was done he chopped the board into pieces.

First he split the board into pieces, splitting between and W and I. (All splits going from left to right not the reverse.)

Then he split the boards between R and C.

Finally he split the boards between C and Y.

When he had split them at each of these connections, he had ten pieces:

BR
YLW
CLWC
YWKPM
YWBPWAR
IDREFFW
IPQRPYRW
CHDWCWNPQC
IQCABRAWBDC
IGRYLWDRAWBZQRWNZBDW

If Fishy split the boards only between W and I he would have sections measuring  7, 8, 16, 20, 26

If Fishy split the boards only between R and C he would have sections measuring  2, 17, 58

If Fishy split the boards only between C and Y he would have sections measuring 5, 11, 12, 49

If Fishy split the boards between W and I, and between R and C he would have had sections measuring  2, 7, 7, 8, 16, 17, 20

If Fishy split the boards between W and I, and between C and Y he would have had sections measuring  3, 5, 7, 8, 11, 11, 12, 20

If Fishy split the boards between R and C, and between C and Y he would have had sections measuring  2, 4, 5, 7, 10, 49

In summary:

S1 = 7, 8, 16, 20, 26
S2 = 2, 17, 58
S3 = 5, 11, 12, 49
S1S2 = 2, 7, 7, 8, 16,  17, 20
S1S3 =  3, 5, 7, 8, 11, 11, 12, 20
S2S3 =  2, 4, 5, 7, 10, 49

Can you put the pieces back together and then solve the cryptogram?
