Here is page 90 from the vintage booklet The Enterprising Housekeeper [1] from the sixth edition (1906).
Enterprise
Bone, Shell and Corn Mills
Best All Around Mills on the Market
It is a well-known fact that ground bones and shells, cracked corn, etc., are excellent for poultry. These Mills are especially adapted to grinding Bones (when dry only), Oyster and other Shells, Corn, Roots, Bark, Grain, Salt, etc.
Ground Bone is one of the best fertilizers, and the Mills will soon pay for themselves for that purpose alone.
Our No. 650 commends itself to those who wish to save space. The ease with which it may be screwed or fastened to the wall, post, etc., is evident from a glance at the illustration.
These Mills are not intended for Grinding “Green Bones”
“Green Bones” can only be shaved, not Ground
