How the Carnation Insures Variation / 



This direct color photograph print, greatly enlarged, 



shows that the carnation has perfected a device for insuring 



variation equally ingenious as the geranium's. This photograph 



shows the pistil, arising from the yellowish egg nest, 



closed and unreceptive at the time that the pollen, 



which may be seen on the two stamens at its 



right, is ready for distribution.
