than those from seeds from the stem or tip end ; plants from seed 

 from the stem end produce nearly the same number of pods as 

 those from the tip end seeds. 



Experiments with Peppers. 



The work with peppers as material in plant breeding was be- 

 gun in the autumn of 1907, when a large number of commercial 

 varieties were started in the greenhouse where a study was 

 made of varietal characteristics and many crosses secured. In 

 May a set of the varieties was transplanted to the field, together 

 with a similar set including the crosses grown from seed in 

 order to compare the effect of indoor and outdoor conditions 

 upon the plants. 



Four types of the pepper plants are shown in Plate XXVIII. 

 These plants were removed from the field and kept in pots until 

 the foliage recovered from the wilting and brought together for 

 the photograph. The plant (No. 11) at the extreme left is one 

 with the stems long, slender and unable to grow upright, thus 

 ha\ing the habit of a pendent or "weeping" plant. The next 

 (No. 34) is styled a medium-sized plant, while the next plant 

 (U. S. D. A. 22806) to its right, seed of which was obtained 

 from the United States Department of Agriculture, is a true 

 standard. No. 21 at the extreme right is a typical dwarf. 



Six types of foliage are shown in Plate XXIX, the differences 

 being very evident between the extremes given at i and 6. 

 Besides the number and shape of the leaves, easily observed as 

 the eye runs over the six samples, there are other differences that 

 obtain as shades of green and thickness, not recorded in the 

 picture. 



Plate? XXX and XXXI are of the fruits, either one or a small 

 cluster for each commercial variety. It is seen that the number 

 of variations in size and shape is great, and when the many 

 colors and shades are added the assemblage is very striking to 

 the eye.
