If this is the case, it is probably due to the fact that the squares appear more prominently to the eye than do the bars, and it would seem that the best kind of presentation might be made by using much wider bars so that the bars would be easily seen. Bars can be made as wide as some of the squares seen in Fig. 19 and, if it seems best, thie bars could be made in outline rather than in solid

black. Wide bars would give a striking visual effect and yet they would vary in one dimension only, so that relative proportions could be easily judged. Wide bars would probably have all the advantages and none of the disadvantages of the methods of either Fig. 19 or Fig. 20. Instead of showing the data of Fig. 19 by either bars or squares, another method would show pictures of bales in rows of different lengths, on the general scheme of Fig. 41. The rows would be the same as the broad horizontal bars, but their numerical interpretation would be less abstract.
