of "Yellow Prince"' upon ''Golden Fig" after the formula, 75// 

 148/173. The fruits are unusually smooth, slightly broader in 

 the blossom-half as shown at 6. Here again in itself this 

 strain has no special merit, but offers an opiX)rtunity to build 

 upon a form of fruit with a long axis so as to obtain a com- 

 mercial variety that should be generally acceptable. 



HYBRID TOMATOES. 



Upon Strip II was grown a block of "Magnus-Currant" hy- 

 brids in the first and second generations with a few specimen 

 plants of the parents. The following table gives a few of the 

 results in stem, leaf, and fruit, with the 191 second generation 

 plants :

Development of tiik Okka Fruit. 



Plate XVII shows in the lower portion, from left to right, 

 a set of fifteen fruits of the grooved type in various stages of 

 development (i, 5, 10, etc.) from the time when the flower 

 falls, on to the matured pod (15). In like manner, in reverse 

 order, in the upper row is shown a similar set of the smooth 

 type of fruit. 



At the time of blooming, the fruit stalk averages 25 mm. ± 

 in length and it increases a comparatively small amount through- 

 out the development of the fruit, attaining only 35 mm. ± at 

 maturity. By running the eye along the two sets of fruits above 

 mentioned in the plate, the fact as stated is fully established. 



The receptacle increases from 13-14 mm. ± to 24-29 mm. 

 ± or, in general, the base of the fruit doubles its width during 

 its development. There is usually quite a constriction in the 

 fruit just below the base, which is well shown in lx)th sets in the 

 engraving. 



Measurements of the growing fruits taken near the middle 

 show that there is an expansion of the fruit from 10 mm. to 

 25 mm. ± ,*or two and a half times its width, when leaving 

 the bud condition. 



The greatest growth in the okra fruit is, of course, in length, 

 this amount depending upon whether the kind is "short-podded"
