The summer of 1850 was unusually cool and unfavorable for wheat. It will
be seen that on all the plots the yield of grain is considerably lower
than last year, with a greater growth of straw.

You will notice that 10_b_, which last year gave, with ammonia-salts
alone, 32-1/4 bushels, this year, with superphosphate, potash, soda, and
sulphate of magnesia, gives less than 18 bushels, while the adjoining
plot, dressed with ammonia, gives nearly 27 bushels. In other words, the
ammonia alone gives 9 bushels per acre more than this large dressing of
superphosphate, potash, etc.

On the three plots, 8_a_, 8_b_ and 9_a_, a dressing of ammonia-salts
alone gives in _each case_, a larger yield, both of grain and straw,
than the 14 tons of barn-yard manure on plot 2. And recollect that this
plot has now received 98 tons of manure in seven years.

"That," said the Doctor, "is certainly a very remarkable fact."

"It is so," said the Deacon.

"But what of it?" asked the Squire, "even the Professor, here, does not
advise the use of ammonia-salts for wheat."

"That is so," said I, "but perhaps I am mistaken. Such facts as those
just given, though I have been acquainted with them for many years,
sometimes incline me to doubt the soundness of my conclusions. Still, on
the whole, I think I am right."

"We all know," said the Deacon, "that you have great respect for your
own opinions."

"Never mind all that," said the Doctor, "but tell us
