Before men learnt to count, the shepherd guarded against the loss of a she from his flock by making a tally of the flock. As each sheep passed through the gate in the morning, on the way to the grazing land, the shepherd cut notch in his stick. At nightfall, when the flock returned to the fold, checked his sheep against the tally by running his fìnger along the notche moving from notch to notch as each sheep passed. The tally stick served i purpose just as well as counting the flock serves the shepherd today. T tally could be passed from hand to hand almost as easily as numbers a now passed by word of mouth (or written down); it constituted a reasonat permanent flock record, and so long as flocks remained quite small there w no necessity to mother the invention of a new system of recording.
