"O'er Waiting Harpstrings of the Mind" is pretty good, quite fair to middling--the whole seven of the stanzas--but repetition would be certain to take the excitement out of it in the course of time, even if there were fourteen, and then it would sound like the multiplication table, and would cease to save.

The congregation would be perfectly sure to get tired; in fact, did get tired--hence the compulsory By-law.

It is a measure born of experience, not foresight.
The By-laws say that "if a solo singer shall neglect or refuse to sing alone" one of those three hymns as often as once a month, and oftener if so directed by the Board of Directors--which is Mrs.Eddy--the singer's salary shall be stopped.

It is circumstantial evidence that some soloists neglected this sacrament and others refused it.

At least that is the charitable view to take of it.
