Chestnut

This chestnut must be the last tree of several. Chestnuts require cross-pollination in order to produce nuts. So you need at least two, maybe three trees. There are no known chestnuts within some miles. As a result each year we clean up the spiny covers with no nuts inside!

And a "rose cottage" photo.

Face the Shinn House.  and line up the peaks so you are standing in this same spot. You will note that the house had not had its addition in the back yet. 

And you will notice a huge rose, possibly a Lady Banks rose covering the house. Roses did very well in California and the Lady Banks rose can get quite large. 

Charles Howard Shinn wrote about rose covered cottages of California in February 1891, when he was an inspector of the University of California Experiment stations. On page 48, there is a picture of the other side of the Shinn House with a huge La Marque rose.
