Wyoming pollinated with Aminia. — Four clusters which were 

 tested, were rated 0, 0, 0, 8, respectively. Average rating 2. 



Wyoming pollinated with Brighton. — Six clusters which were 

 tested, were rated 0, 0, 0, 0, 22, 50, respectively. Average rat- 

 ing 12. 



Wyoming pollinated with Catawha. — One cluster which was 

 tested formed a perfect cluster of fruit. It was rated 100. 



Wyo7ning as a fertilizer. — It was tried as a fertilizer on two 

 self-sterile sorts, Aminia, page 369, and Brighton, page 371. 



SUMIVIARY OF RESULTS. 



In the following summary of the results of the investigation 

 the data which have been given on preceding pages are arranged 

 in Table II with reference to the ability of each variety to fertilize 

 the seK-sterile sorts upon which it was tried as compared with its 

 ability to fertilize itself, and in Table III with reference to the 

 varying degrees of fruitfulness which the self-sterile varieties ex- 

 hibit when they are supplied with pollen from various varieties, 

 some of which are more or less self-sterile and others self-fertile. 



Explanation of tables. — The x between two names indicates 

 that the variety following the x was used in pollinating the variety 

 whose name appears before the x. Thus, Brighton x Aminia in- 

 dicates that the Brighton clusters were pollinated with Aminia 

 pollen in th,e manner described on page 364. The rating is on the 

 scale of 100 points as previously explained, a perfectly formed 

 and perfectly filled cluster ranking 100. The average rating is 

 shown graphically and the number of tested clusters upon which 

 the average is based is also stated. The highest rating which any 

 single cluster in the test received is also given. 



" Self -pollinated " indicates that the tested clusters were simply 

 kept covered in paper bags during the blooming season. Some- 

 times the self-pollination was performed by hand, pollen from 

 another vine of the same kind being applied in the manner de- 

 scribed in the foot-note, page 369. Such tests are marked " hand 

 pollinated " in the table.
