Frelieghsburg, Ontario, Aug., 22, '87.

E. F. Smith, Esq.,

Dear Sir:

* * * The methods of analysis employed by us
were the same as would be employed by any good chemist and
vegetable histologist.  If you instruct the Department Chemist
that you want certain elements determined in the wood, he
will be sure to give you an analysis that will compare with
those published by us and by others.  The elements you
enumerate are those which should be determined; others would
be of little of no value.  I would suggest that you will
find a soil analysis, however accurately made, by no means a
correct indication of the capacity of the soil in meeting the
requirements of nutrition.  If you are to get exact data in
this direction, you will probably find it necessary to insitute
a careful series of feeding experiments to compare with
a parallel series of analyses of the wood and fruit.

You are probably aware of the fact that our mode of
treatment has been tried in New Jersey for several years past,
with a very considerabel degree of success.
* * * * 
Respectfully yours,

D. P. Penhallow.
