Mr. Brimhall. Salsoda made strong enough will kill t lem. 
One pound to a gallon of rainwater is about right. mae 
Mr. Gould. Would leave undisturbed the little wasp nests 
before mentioned, as enemies of the lice. For mice cats are good. 
Mice have never hurt my trees. I even have grass growing near - 
them, and the cats keep off the mice. Rats are increasing with us. 
They have found out how to bark trees and I don’t know what to 
do with them. 
Mr. Storrs. Washing with tobacco solution has had the best 
effect in my experience. 
At this point the society adjourned to meet at 1:30 p. m.

REPORT ON POTATOES. 
The meeting was called to order by President Smith at 1:45. Mr. 
Sias being absent his report on potatoes was read by the Secretary. 
It was as follows: 
Prof. C. Y. Lacy, 
Dear Srr:—Were it not for the fact that you had rendered it incumbent upon 
me, by your liberal donation of some twenty choice varieties of the Irish potato, 
to be distributed among the members of the Olmsted Co. Horticultural Society, 
to say something on this important subject, I would not intrude my crude 
thoughts upon this intelligent body of horticulturists at this time. I have too 
much respect for the the feelings of this society, to inflict upon them a long, dry 
paper on the theory and practice of potato culture in Minnesota—fertilizers, &e. 
Will merely give a bit of my experience, and a prediction or two, and I am done.
