I think it was 14 every seven or eight seconds and say this is the dust 15 level now and so forth all during an interval, and 16 plot a pattern for us over a 15-minute interval. 17 So we would have almost instantaneous 18 appreciation for how much dust there was in the 19 environment at any one time. 20 Q So were you able, then, to see how quickly 21 the dust level rose and then fell off?
