Dear Sir:

I have received your kind favor of the 26th. in re-
gard to your microscopial examinations fo swine-plague material
upon which Dr. Gerth bases his very positive and sweeping conclu-
sions in regard to this disease, I had an idea before receiving
your letter that his conclusions were given entirely on his own
authority and I am glad to have this idea confirmed by your letter.

We have recently made some important progress in the study of
swine-plague and as soon as the weather become settled, we will
be glad to accept your offer and confrim our conclusions by inves-
tigations in your State. I think you will see why it is not advis-
able in the present state of the investigations of the past and
who is unfamiliar with our researches to make the investigations
in Nebraska.

Very respectfully,
signature
Chief of Bureau.
