In the month of July, 1876, Miss Brown was engaged to sing at the "Great Sunday-school Parliament" held on Wellesley, one of the famous Thousand Islands, in the River St. Lawrence. The now much-lamented Professor P.P. Bliss (who had become so eminent as a composer of popular sacred songs), his talented wife, and Miss Brown, were the leading singers and soloists on the occasion mentioned. The two former failing to arrive in time, the musical exercises, which were of a very fine order, were arranged, and for a while conducted, by Miss Brown. Mr. and Mrs. Bliss, however, arrived some time after the sessions had begun, and then participated in the singing. At this memorable gathering of Christian people from all parts of the United States and Canada, Miss Brown, in the display of fine musical powers, won new laurels; and her charming singing was made the subject of frequent and very complimentary allusion by newspaper correspondents writing from the island. In a handsome volume since published by the director of the "Parliament," and which is a record of its proceedings, she is several times creditably mentioned. The following is one of many like notices which the musical exercises mentioned elicited:-- ... "As to the singing of Professor Bliss and Miss Nellie Brown, it seems as though we are all in the third heaven at once, and that it is almost sacrilege to come down to meaner things." Said Andrew Fletcher, "I knew a very wise man that believed, that, if a man were permitted to make all the ballads, he need not care who should make the laws, of the nation." This certainly was placing a very high, but perhaps not a much too high, estimate on the song-writing power. As coming next in greatness to the composers of meritorious popular ballads, we may mention those accomplished persons, who, possessing sweetly-toned, sympathetic voices, and evincing by their mode of expression a ready, a full conception of the author's meaning, have, in an eminent degree, the power to correctly, charmingly render them. In this form of musical expression Miss Brown delights her audiences not less than in her rendition of songs of a more pretentious character. In singing the former she exhibits a most winning _naivete_, enters wholly into the spirit of the song, and with a full, pleasing voice, impresses deeply its melody and meaning upon the hearts of her hearers, thus exhibiting the highest kind of lyric eloquence. As a singer, then, of ballads alone, she would take high rank in the musical profession, even if she did not excel--it has been seen that she does--in the rendering of songs of a more technical character.
