MR. BERNATH: No, not too much, if it's callused up good, if the union is hard enough. And then, of course, you put the glass on, and then you keep these grafts in the greenhouse. But don't forget now, something that is important, when you graft these. Here we have a greenhouse over us. This little box represents the batch of grafts. Don't forget you have to shade them. If you didn't shade these, they would burn to a crisp. I have lost several hundred blue spruce grafts by going away on a day when it was cloudy and I forgot to tell Mrs. Bernath, "If the sun comes out, raise the sash." When I came home, this part of the greenhouse was shaded; now, in this corner here I think it was around 250 beautiful grafts but the next day I was going to take them out. They were burnt to a crisp. I saved a few trees right where it was shady.
MR. CALDWELL: The blue spruce are grafted by the same method?
MR. BERNATH: Yes, I use this method for inside grafting for everything.
MR. CALDWELL: Use this method for shagbarks the same way?
MR. BERNATH: Yes, same way with hickories and oaks.
MR. WEBER: What sort of shading element do you use? Anything real tight, or how?
MR. BERNATH: Yes, air tight. The grafting case has got to be air tight.
MR. WEBER: The shade?
MR. BERNATH: Oh, any kind of cloth, cheesecloth, muslin. I know that will do it.
MR. CHASE: Whitewash?
