Chemawa Prints Project Day 2

I completed the scanning of CH 063 -- CH 200. I fixed the labeling problem I found yesterday: I switched the second CH 040 to CH 041. I found that CH 118 was a duplicate of CH 045, and labeled this in the Metadata. I continue to fill in the Metadata alongside the photos but have prioritized the digitizing (scanned through CH 200, 'Title' through CH 180, 'Date' through CH 128, 'filename' through CH 128). I added the 'Subject' column, as well. To "Description' for CH 150, I added "W.F. WELLS. & SONS, INC THREE RIVERS, MICHIGAN."

A few of the photos were labeled in the Metadata with "Date inferred:..." I marked them with yellow in the first Metadata sheet. I do not know from which these dates came. Should I use these inferred dates for the Date column? 

Today I came across man photos of industrial work and a few of domestic work. There is evidence of strict gender rules because there are no photos of women doing industrial work (woodwork, operating machinery, metalwork) nor of men dong domestic work (sewing). There was one photo that could be an exception: CH 146 shows male students having a tea party. I also came across the first portrait (CH 086). It depicts a young man with clothing that says "CHEMAWA." Another interesting find was CH 112. It shows two men in uniform (police officers?): one writing something while bent down and the other standing up and looking down at him. They are next to a Volkswagen Bug with its door open. Handwritten across the top and bottom are the words, "HAVE YOUR ANNUAL SMALL APPLIANCE SAFETY CHECK." The date is May 1962. 

Three photos stood out to me in particular: one of students doing industrial work (CH 150), one of a male dancing in front of a Christmas tree  and model of Santa Clause, his sleigh, and reindeer (CH 187) (DEC 63), and a few others (~CH 194) of people (a few students?) getting off of a plane. CH 158 also stood out to me because it shows model tipis, carvings, and padles all modeled on a table. I would like to know more about the context of this photos and the objects in it.
