When the color begins to appear it commonly means that the mold is producing spores. The spores are nearly always so small and light as to be blown easily by the wind, and in this way they are carried to and fro. The air in any household is almost sure to be filled with them in greater or less abundance, as can easily be proved. See experiments 6-8, pp. 3^2-273.
