The record of attendance is regulated by the use of checks. Each member of the chorus is assigned a number. As they come to rehearsal, service, or concert, the singer removes the check on which is his number from the board upon which it hangs and gives it to the person appointed to receive it as he passes up the stairway to his seat in the choir. When the numbers are checked up at the close of the evening, the checks which have not been removed from the board are marked "absent." The bill for sheet music for one year is something between $400 and $500. To care for so much music would be no light task if it were not reduced to a science. The music is in charge of the chorus librarian, who gives to each member an envelope stamped with his number and containing all the sheet music used by the chorus. Each member is responsible for his music, so that the system resolves itself into simplicity itself. In the Lower Temple enclosed closets are built in the wall, divided into sections, in which the envelopes are kept by their numbers, so that it is but the work of a moment to find the music for any singer. An insurance of $1,200 is carried on the music. Typical of the spirit of self-sacrifice that animates the chorus is the fact that for nearly ten years after the choir was organized, one of the members, in order to reduce the expense for sheet music, copied on a mimeograph all the music used by the members. It was a gigantic task, but he never faltered while the need was felt. In order to avoid confusion both in rehearsals and at each service, every singer has an appointed seat. There is also a system of signals employed by the organist, clearly understood and promptly responded to by the chorus, for rising, resuming their seats, and for any other duty. This regularity of movement, the precision with which the great choir leads the attitudes and voices of the congregation in all the musical services, the entire absence of confusion, impresses the thoroughness of the chorus drill upon every one, and adds greatly to the effectiveness and decorum of the service. Most remarkable of all the work of the chorus, perhaps, is the fact that it has not only paid its way, but it has in addition contributed financially to the help of the church. Most choral societies have to be supported by guarantors, or friends or members must reach down in their pockets and make up the deficits that occur with unpleasant regularity. But the chorus of The Temple has borne its own expenses and at various times contributed to the church work. At the annual banquet in 1905, the following statement was made of the financial history of the chorus since 1892:
