The chipmunk plays an important role in establishing the proper measure of things. When the earth was new and the year was to be set in its length, a creation council had to determine how many moons would occur in this time period. Both the turkey and the partridge suggested that the number of moons be equal to the lunar spots on their tails, but the council considered that there were be far too many months in a year if that were adopted. Then Chipmunk came forward and said that the number of moons should be equal to the number of stripes on his back, with the black stripes defining the warm months, and the white stripes those of the cold time of year. 
In another story, the chipmunk regulates the proportion of things in space as well. When Trickster was first in the world, his penis was so long that he had to carry it in a box on his back. However, someone kept teasing him about it, but Trickster could not see who it was. Finally, he ran in the direction of the noise and saw a chipmunk run into the hollow of a log. He told his penis that since it had been abused, it could go after the offender, and he stuck it into the hole in the log. However, he could not seem to get to the end of it, and when he reeled his penis back in, he found that the chipmunk had gnawed the bulk of it off. The enraged Trickster pulled the chipmunk out and flattened him.2
Thus the chipmunk, by its nature, trims back things that are too long in space and time and gives them their proper shape and order.
