having had a letter from you in which you expressed the hope that I 
would be able to visit Mr. Carl H. Hartmann, a correspondent of yours

January 1,1889, During the same day a full-grown female Icerya was 
discovered in the woods about three miles from this place on Acacia

found. I visited the Range nursery the following day and met the son 
and the brother of Mr. Hartmann, who himself had died from the effects
