The oat-harvest began, and all the men were a-field under a monochromatic Lammas sky, amid the trembling air and short shadows of noon. Indoors nothing was to be heard save the droning of blue-bottle flies; out-of-doors the whetting of scythes and the hiss of tressy oat-ears rubbing together as their perpendicular stalks of amber-yellow fell heavily to each swath.
After a while, oxidation would weaken a can to the point where some lucky rat could bite through it and find himself a meal. Then he could move the empty can aside and gnaw the next one in the pile, and the cycle would begin again. It kept the rats fed almost as well as an automatic machine might have. The tunnel was an endless monochromatic world that was both artificial and natural.
It may be grown in full isolation, and carefully selected, all red or nearly monochromatic samples being rooted out long before blooming, but nevertheless the seed will always produce some red roots. The most careful selection, pursued through a number of years, has not been sufficient to get rid of this regular occurrence of reversionary individuals.
In the following discussion it will be found most convenient to give a summary of what is known concerning them, and follow this by a consideration of the detailed evidence obtained experimentally, which supports the usage cited. The striped variety of the larkspur of our gardens is known to produce monochromatic flowers, in addition to striped ones.
If, however, the retardation be only equivalent to half a wave length, the intensity of the light will be decreased. Thus, then, with a ray of monochromatic light it will be seen that the effect of difference in the thickness of the film will be to alter the intensity of the reflected ray, but with a white light composed of several colors the result will be more complicated.
With monochromatic light the rings would be simply bright and black the bright rings occurring at those thicknesses of the spar which cause the rays to conspire; the black rings at those thicknesses which cause them to quench each other. Turning the analyzer 90° round, we obtain the complementary phenomena.
It is easy to see that this retardation of the one end of the wave must cause it to swing round and change its front, so that when the wave has fully entered the glass its course is oblique to its original direction. According to the undulatory theory, light is thus refracted. With these considerations to guide us, let us follow the course of a beam of monochromatic light through our glass prism.
Gem-engraving also, although more recent, was in various forms practised in Etruria. Equally dependent on the Greeks, but otherwise quite on a level with the workers in the plastic arts, were the Etruscan designers and painters, who manifested extraordinary activity both in outline-drawing on metal and in monochromatic fresco-painting. Campanian and Sabellian
When white light, therefore, passes through the slit the various colours are not superposed, and instead of a series of monochromatic bands, separated from each other by intervals of darkness, we have a series of coloured spectra placed side by side.
A corolla cannot be at once monochromatic and striped, nor can the same part of a stem be twisted and straight. But neighboring organs may show the opposite attributes side by side.
