grow and soon died; one bud grew three inches; and two buds
grew eight to ten inches.  All turned yellow and looked sickly
in August of the same year and I pulled up the trees and 
burned them."  Letter of Sept. 30, 1887. [Here was a great
opportunity lost! Mr. LaFleur admits that the stocks should
have been left in the ground and allowed to grow.  Then he
might have learned whether yellows can be communicated to
healthy stocks by inserting diseased buds.  It did not occur 
to him at the time.  This is the very thing to be determined,
for a diseased bud could not be expected to make a very healthy
growth.  Yet it might not give disease to the stock.  If it
did, it would be good proof of the contagious nature of yellows.
He has made no other experiments.]

Dr. F. S. Dunlap, of Delaware City, says: "I have budded
in different years from twenty-five to thirty trees, with 
the result invariably of giving yellows to the tree budded."*
He is also sure he has conveyed the disease by the saw and the
pruning knife.  He has tried this on at least thirty trees.

"I have applied nitrate of potash, kainit, and wood ashes
but have not suceeded in arresting or preventing the disease."

*Dr. Henry Ridgely many years ago budded a 
good many trees from a choice-looking premature

none fruited,- conversation in Aug. 1888. at Dover, Del.
