Plant By the Moon Grandad refused to plant potatoes until the moon was, just ritfht. Saul they wouldn't "do well." Refused to listen to modern view that it was all superstition. Mow science comes to the fore with the announcement that grandad was rifcht. It seems that scientists now understand under-stand the natui-j of moonlight in connection with plant growth and are able to duplicate in the laboratory the effects of moonlight. Moonlight is reflected sunlight but differs from sunlight in that it is polarized light, that is, light waves which vibrato in one direction, whereas ordinary light waves vibrate in all directions. It has been found that certain plant growth is increased by polarized light. So grandad was justified in merely getting the ground ready for planting and then going fishing until the moon came his way in the proper quarter. In ancient times, when human life depended largoiy on the success or failure of crops, much attention was given to the time it was planted and comparisons made. The originators of the moon-phase idea knew by experience that in certain quarters of the moon they were sure of a bumper crop. They knew the effect but not the cause. Even the cfirly Scripture speaks of "the precious things brought forth by the sun, and the precious things put forth by the moon." Biblical commentators have not known how to 'deal with the passage. Along comes science, and both Scripture and grandad can say, "I told you so." Dearborn Independent.
