The article mentions and quotes from a letter written by Mora on October 4, 1904:

I am back at Tolchaco for a couple of weeks, in which time I am going to make a tour of this part of the reservation to sketch and photograph. After that I'm going to saddle up once more and cross the Painted Desert for the third time into Hopi Land. This time I will go straight to Walpi where I expect to stay about a month, painting and sketching and living with E. A. Burbank, the well known Indian painter. I met him at Oraibi and he seems to have taken quite a liking to me for he insists on my going to Walpi and then going around with him to the other Indian tribes.

During my stay of four days at Walpi, I got in some good licks; making several pen and inks and two water colors, ?one a portrait of a Hopi maiden with her hair done up in the proper Hopi style for maidens. Burbank has got these Indians trained fine and you can get them to pose, a thing I couldn't do at Oraibi. Of course you've to pay them, but there I'm going to do it, for one doesn't get a chance like this every day. ?Around town for pen and inks, it is just simply an artists delight!
