Showing lime pebbles and effects of frost on tile. vantage of the round tile is that if the ends do not fit closely in one position it can be turned around any dis- tance until a close fit is obtained. Another point to be considered in favor of the round tile is its greater strength. In making a tile six-sided, the thickness of the walls is reduced nearly one half at the center of each side so that its strength is proportionately diminished. As the result of some crushing trials with round and six-sided tiles selected with as nearly the same hardness as possible, it.
