| Donovan stretching | 
We have a heritage yellow cherry tree on the place. It must be about 75  years old, for it was a good size when my parents and I moved up here in  1951. The cherries are deliciously sweet.  My parents, not being  horticulturists with a bent toward pruning, allowed it to continue its  upward yearning until many of its bearing branches were out of reach.   Currently, only half of the tree survives, the other half having split  off years ago. It's ancient but rugged, despite an occasional branch dying off.  Toward the end of July it bore heavily and Jay, my son Donovan and I  made an effort to harvest as many as we could reach from the old wooden  picking ladder.  Donovan is the tallest and has a great reach, so he  was tagged to harvest the higher hanging fruit.

As I said, this is a heritage cherry, which means it is fungible and  begins to turn brown a day after being picked.  I thought  only one yellow  cherry variety existed until a few years ago when I came into possession  of a wonderful large tome titled 
The Cherries of New York, by U.P.  Hedrick, published in 1915, with beautiful color plates.  Being a dealer  of rare books at the time and living far away from this particular old  tree, I perused it and then sold it for a good price to a  horticulturist in Australia.  
Now I wish I knew the cherry's variety and history.  Alas, 
The Cherries of  New York is not a book one finds in the public library.  But wait.  Google  has scanned books published before 1923 from major university  libraries for our free download and use.  I do a lot of research on that  site.  And sure enough, there is 
The Cherries of New York. None of  the color plates is of a white or yellow cherry, but of numerous long-forgotten  black, red and orange varieties.  Toward the back of the book are short paragraphs on  lesser-known varieties.  And here I find the white and yellow cherries.   So, is this tree a White French Guigne (1851),  whose flesh is  creamy-white,  tender, melting, sweet; ripens in middle of July [in  New York State]; or perhaps Fraser's White Tartarian (1803), pale  yellow, approaching amber on the exposed cheek, with flesh juicy,  pleasant, brisk subacid becoming sweet.  Or the White Transparent  (1831), The White Spanish (1790), The White Mazzard (1838), The White  Hungarian (1831), or The White French (1881).  Cherry varieties enough  to make one dizzy. Or maybe it's the Yellow Glass (1903), introduced  from North Silesia by Professor Budd of Ames, Iowa, its skin light lemon  in color with firm yellow flesh, meaty, sweet, with colorless juice,  and of good quality.  That fits it well.  But we'll never really know.
So, we ate some and dried the rest in our dehydrator for future use.   Chewy, sweet with just a hint of tartness.  And very brown and wrinkled.
