From the local news column of the New Hartford Tribune, the source of perfectly delightful gossip.
“Miss Smith, manager of Esperanza Farm met with an accident Tuesday morning while delivering milk to her neighbors. The sleigh turned over near Miss Kate F. Holcomb’s throwing out the contents. The horse continued on its way to G.C. Kellogg’s where it was caught and placed in the stables. The damages were slight. The cold and high winds were severe with zero weather.”
Miss Smith was Fannie, (Julie’s daughter). What is interesting about this comment is that it conclusively shows that Fannie at least was living here year-round. She lived in the cottage across the lane. This parcel, since sold, was the site of successful, model dairy farm run by Fannie. She was very interested in the science of improving dairy farming and held a voluminous correspondence on the subject with the various state agricultural stations, Cornell University and other institutions. It must, however, have been something of a change from her earlier career with Steinway (pianos).

Was she living in the still-existing (if amazingly modified) “Cottage” or in the Bungalow? And, in either case, I wonder if the building was much more winterized than the Big House? One would hope so. . .
I am thinking that perhaps she was living in the Cottage? I can’t imagine that the Bungalow was ever winterized… But the Cottage would have been manageable, and it makes sense given her interests. I think at one point a greenhouse or cold frame was attached to it. It is perhaps telling that the vast majority of pictures of her are taken on the Cottage grounds not Esperanza’s, in contrast with Helen or Lucy. Of course, another question then…does the sleigh come down from Brockport with her? Or was it another sleigh or…?
