PLATE 12 



Fig. 1. Showing extent to which the leaves can draw on the water in the fruit. 

 Both shoots were cut at the same time and had approximately the same leaf 

 area. All cuts were sealed with vaseline. The fresh-appearing leaves on the 

 shoot at the left have maintained themselves at the expense of water in the 

 fruit. Note the difference in reflection of light from the two fruits. See 

 Experiment 1. 



Fig. 2. Photograph illustrating an orange shoot so arranged as to be able to 

 draw water from one end and eosin solution through the pared apex of a small 

 fruit at the other. In spite of this double supply a large water deficit occurred, 

 and eosin was drawn back from the container on the right to the leaf next to the 

 water container on the left. See Experiment 6.
