The Spots on the Cigar.

The pale round spots, about as large in circumference as a tack-bead, that one sees on cigars now and then, are said to be caused by dew drops and rain drops, that act as burning glasses when the sun shines through them on the green tobacco leaf. Be that as it may, the florists declare that palms are often burned by knobs and corrugations in the glass roofs of their greenhouses, as these irregularities tend to focus the sun’s rays. The * effect of this strong heat on the palm leaf—which is as sensitive to heat as it is to cold—is to cause a rusty brown spot to appear on the green. Sometimes the apparent motion of the sun, in passing westward, will trace a line of scorch across ‘the leaf. Other plants are less susceptible to sue rays.
