Was searching for info on minerals and came across this.

Gem Stones of the United States - The government stamp reads, I believe, March 3, 1949

Geological survey bulletin.

Many of you have probably seen it but for those who haven't it's interesting.

Especially the geographical distribution of deposits.

Love reading old technical publications.
