She, however, continued to come whenever I was present, growing stronger each time, apparently demanding recognition, and showing plainly that she did not mean to be put aside for any one. At length I said, "Will you tell me who you are?" She replied, "I am Bertha; you are my uncle; I am your niece;" at the same time holding out her hand about three feet from the floor. As I did not understand this, she subsequently explained it by coming out as a child about four years old, that being the age, as I afterward learned, when she passed to the other life. As I was a stranger to the medium and all present (except one, and that one knew nothing of my relatives), it does not seem probable that the medium could have known anything about her. The individuality of Bertha is very striking, bearing little or no resemblance to any other materialized form which I have seen. She never comes shrouded in a profusion of drapery; on the contrary, she appears scantily but richly dressed, wearing a short skirt and close-fitting waist, with short sleeves, leaving her finely-rounded arms bare. She never wears a head-dress; her long silken hair floats freely round her shoulders. In form and feature she is the embodiment of girlhood, with a playful disposition which leads her to make amusing remarks, at times, about those who come within her mental atmosphere. Her figure is compactly built, and well proportioned, with a remarkably fine face, the expression of which, at times, surpasses anything I have ever seen. She is much shorter than the medium, as the following measurements will show:-- Mrs. H. B. Fay, medium, height, 5 ft. 4 in. Bertha, materialized form, height, 4 ft. 9-1/4 in. Male form (to Mr. Tallman), height, 5 ft. 9-1/4 in. Difference between Mrs. Fay and Bertha, 6-3/4 in. Difference between Mrs. Fay and male form, 5-1/4 in. Difference between Bertha and male form, 12 in. These measurements were taken by means of an upright staff with a cross piece at right angles, and I was assisted by a gentleman who is a thorough skeptic. Care was taken to have the forms stand perfectly upright, so that there could be no mistake as to accuracy. I have given this brief sketch of Bertha as I shall have occasion to allude to her hereafter, for I am greatly indebted to her for much that I have learned about materialization. She has taught me that the ability to communicate intelligently depends upon the use these beings can make of our aromal emanations, or magnetism; that frequent association with us is necessary to enable them to gain control of material elements, and that where the relations are harmonious they gather strength every time they come in contact with us.
