Consists only of his handwritten Hopi dictionary.

It appears that some, maybe most, of the handwriting in this volume is H. R. Voth's. The "notes on Hopi ceremonies" at the beginning is clearly Voth's handwriting.

The end of the volume contains  copies of a few letters written by J. B. Frey.

It's not clear whether the dictionary entries are in Voth's or Frey's handwriting.

Box 1 is mostly materials related to his Hopi gospel song compilation. Includes several audio tape reels.

Box 2 has more audio tape reels, more Hopi hymnal related material, photocopy of an autobiography by Mabel Suderman, a few photos, a few of what look like sermon outlines.

Box 3 is later additions.
