It was such a charming home!--my new one; a fine great house, with pictures, and delicate decorations, and rich furniture, and no gloom anywhere, but all the wilderness of dainty colors lit up with flooding sunshine; and the spacious grounds around it, and the great garden--oh, greensward, and noble trees, and flowers, no end! And I was the same as a member of the family; and they loved me, and petted me, and did not give me a new name, but called me by my old one that was dear to me because my mother had given it me--Aileen Mavourneen. She got it out of a song; and the Grays knew that song, and said it was a beautiful name. Mrs. Gray was thirty, and so sweet and so lovely, you cannot imagine it; and Sadie was ten, and just like her mother, just a darling slender little copy of her, with auburn tails down her back, and short frocks; and the baby was a year old, and plump and dimpled, and fond of me, and never could get enough of hauling on my tail, and hugging me, and laughing out its innocent happiness; and Mr. Gray was thirty-eight, and tall and slender and handsome, a little bald in front, alert, quick in his movements, businesslike, prompt, decided, unsentimental, and with that kind of trim-chiselled face that just seems to glint and sparkle with frosty intellectuality! He was a renowned scientist. I do not know what the word means, but my mother would know how to use it and get effects. She would know how to depress a rat-terrier with it and make a lap-dog look sorry he came. But that is not the best one; the best one was Laboratory. My mother could organize a Trust on that one that would skin the tax-collars off the whole herd. The laboratory was not a book, or a picture, or a place to wash your hands in, as the college president's dog said--no, that is the lavatory; the laboratory is quite different, and is filled with jars, and bottles, and electrics, and wires, and strange machines; and every week other scientists came there and sat in the place, and used the machines, and discussed, and made what they called experiments and discoveries; and often I came, too, and stood around and listened, and tried to learn, for the sake of my mother, and in loving memory of her, although it was a pain to me, as realizing what she was losing out of her life and I gaining nothing at all; for try as I might, I was never able to make anything out of it at all.
