Morris says, regarding the dust influx rate:
"The best measurements have been made by Hans Pettersson, who obtained the figure of 14 million tons per year1."
Morris (1974, p. 152)
Pettersson stood on a mountain top and collected dust there with a device intended for measuring smog levels. He measured the amount of nickel collected, and published calculations based on the assumption that all nickel that he collected was meteoritic in origin. That assumption was wrong and caused his published figures to be a vast overestimate.
Pettersson's calculation resulted in the a figure of about 15 million tons per year. In the very same paper, he indicated that he believed that value to be a "generous" over-estimate, and said that 5 million tons per year was a more likely figure.
Several measurements of higher precision were available from many sources by the time Morris wrote Scientific Creationism. These measurements give the value (for influx rate to the Earth) of about 20,000 to 40,000 tons per year. Multiple measurements (chemical signature of ocean sediments, satellite penetration detectors, microcratering rate of objects left exposed on the lunar surface) all agree on approximately the same value -- nearly three orders of magnitude lower than the value which Morris chose to use.
Morris chose to pick obsolete data with known problems, and call it the "best" measurement available. With the proper values, the expected depth of meteoritic dust on the Moon is less than one foot.
