and a number of others, including the "Ivory" (26) of our own 

 make, are practically colorless from the time the corolla drops, 

 that is, the interior of the fruit is white and the skin enclosing it 

 is transparent. This condition of things continues through 

 the market-maturity period when the white fruits are peculiarly 

 attractive after which a pale lemon (cream) shade begins to ap- 

 pear, first upon the sun-exposed side and culminates in the light 

 orange of maturity. In short, the, at first, colorless fruits de- 

 velop a shade of orange limited to the outer layer that is common 

 to all other kinds when the condition of ripeness is attained. 



The green-fruited plants of common occurrence upon the 

 breeding grounds, frequently have the ''eggs" with very much of 

 green just beneath the colorless skin and diminishing in amount 

 toward the interior of the fruit save in the placentae which some- 

 times are strongly and distinctly green. Among this group, 

 there are all degrees of striping and mottling, the blossom-end 

 frequently being nearly free from the solid green that may 

 obtain at the stem-end. This diversified marking is due to the 

 smaller amount of the green lying close beneath the skin and the 

 color of the lighter flesh shows through the transparent skin. 

 The green fruits while young show as much green beneath the 

 calyx as elsewhere and when of market size the color is only 

 somewhat lighter. As the green fruits ripen, the orange color 

 due to the change of the outer layer makes its appearance in 

 place of the earlier green. 



The "Striped" varieties, instanced in No. 21, have the flesh 

 white and as the "egg" peeps from the large infolding calyx, it is 

 often white for all its exterior but soon pale dark pink lines 

 appear radiating from the blossom-end toward the stem. This 

 coloring is at first limited to the outer cells and as the fruit 

 reaches table-maturity, is scarcely more than skin deep but with 

 the increase in amount, the surface becomes purplish. The calyx 

 does not retard materially the development of the stripes upon 

 the covered portion. 



From the "Striped" it is only a short step to the group with 

 white flesh that has the color quite evenly distributed as in U. S. 

 D. A. No. 27666 from Russia and grown here for the first time. 

 The white flesh is evenly covered with a purple layer which is 

 quite easily peeled off and at the same time splits into an outer 

 practically colorless skin and the under purple-bearing layer. 

 Under the calyx, the fruit surface is pale purple faintly striate 

 throughout, the exposed part being distinctly of a deeper purple. 

 The under surface of the calyx partakes of the striate purple 

 of the fruit surface to which it is applied.
