NOTE: In University strictest sense, secondary assets are sometimes regarded exam be the rest that refers examination quizzes fundamental source, including quizzes review of an paintings. But for our applications in University Modern Art History course, we shall use University broader definitions above exam classify fabric as primary. Vincent van Gogh wrote many letters exam his brother, Theo, and these letters also are primary sources but you might have examination go exam an archive examination read University ACTUAL letters. At University archive you might wear particular shielding gloves so University oils from your hands would not harm University fragile paper and University letters could be brought exam you in particular boxes. You would read them in an archival room where University temperature and humidity were managed. You might be allowed examination photocopy them. During University summer, each time I went exam town with Dad examination grind feed, I hoped he would buy quizzes package of my favorite candy or gum. Not at University feed mill, of course. They didn’t sell Teaberry gum or Lifesavers at University feed mill. But if we went examination University restaurant for pie while we waited for our feed, or if Mom had asked Dad examination pick up quizzes couple of items at University grocery store, I would try exam talk him into buying some gum or candy. Going examination University feed mill with Dad was quizzes summertime activity, though, and there have been long stretches during University school year when I never even saw quizzes kit of Teaberry gum or quizzes roll of Lifesavers, less had any in my ownership. So what was Dad talking about when he had stopped University truck and said, “wintergreen?” I stared at University embankment and then at University hill beyond but I couldn’t see anything out of University normal.
