AOCR1 

Thia ia as poor and amateurish a work 

as I've seen. It would be understandable it 

it emanated from a contributor to the American 

Oryptosram Association, or it it were the opus 

ot the author ot a crypt corner in a detective 

story m&&Uine1 but it is unworllhy or a govez;,ll• 

191ntal a1ency. 

J'irst ot all, the authors ot this book 

know next to nothi111 about the subJect, as evidenced' 

from their bi blio1raphioal. sources and. from their 

manner of writiq •• It they had !!!I. baoqround 

in the buainess, the7 would have exploiteuu(~y 

a ~rtt ¥.droit jJlqiarism) our TM 11-484 and 

11•485 - and they would have made .!.2!!! reference 

,to our texts on Crypt I, II, III and IV. As it 

is, they lifted out an example of a caption code 

on pace 22 from .P&I• 69 ot TM 11•484. Th• charts 

on p&&es 10 to 18 inclusive were compiled from 

material. in TM 11-484. 

Most ot their examples are pseudo•hiatorical, 

since they apparently did not have enoupi material 

from their own· brilliancies. It ia strictly 

Sundaaa-supplement atutr. 

It a work like this ia needed, than tor God's 

sake why isn't the ASA conaulted, aince that's 

our bread and butter occupation! Why there are 

&Ten excellent treatises on this subject written 

by the Germana and the Japanese. 

Recapitulations it certainly stinks.
