ENOLOGICAL STUDIES. 9 



Department of Agriculture, who replied as follows under date of Sep- 

 tember 30, 1909: 



Upon testing the grape I find it to be exceedingly sweet and of excellent quality. 

 I am not positive as to its identification, and desire to give the specimens more careful 

 consideration. 



Again, on October 23, after completing his examination of the fruit, 

 Mr. Brackett wrote as follows, showing quite plainly that this grape 

 is a seedling unknown to the fruit lists: 



The grape which you sent me on September 18, said to be a seedling of Catawba, 

 came duly, and as I wrote you at that time, I was unable to recognize it as any variety 

 with which I am acquainted. I sent specimens to George C. Joscelyn, Fredonia, N. Y., 

 and some to U. P. Hedrick, of the Agricultural Experiment Station, Geneva, N. Y., 

 * * * Neither of these gentlemen recognizes it as any variety they have ever seen. 

 I am therefore inclined to believe it is a seedling. The appearance and flavor of this 

 grape* are exceedingly good, but Professor Hedrick, who examined the last bunch sent 

 out from here, wrote me that he considers it a very poor shipper, so the bunch could 

 not have arrived at his office in very good condition * * *. 



The suggestion made to Mr. Brackett by the writer that this grape 

 was a seedling of Catawba rested upon a report which further inquiry 

 did not support. After making as extensive an inquiry as possible, 

 Mr. Steuk was able to give only a slight history of the grape. It 

 appears that J. F. Munz, of Springfield, Ohio, brought it to the atten- 

 tion of the owner of the vineyard in 1904, and he propagated and 

 planted about 100 vines, from which the samples in question were 

 taken. Mr. Munz states that this seedling was found in a flower bed 

 in which was planted a large collection of seeds received from Roches- 

 ter, N. Y. It is scarcely probable, however, that the grape seed came 

 with the flower seeds. It w r ould appear more probable that grape 

 seeds were accidentally dropped in this bed and that this plant is a 

 chance seedling. 



OTHER VARIETIES EXAMINED FOR SUCROSE. 



The occurrence of sucrose in this seedling grape led naturally to 

 further examinations for this form of sugar, with the result that 

 three other varieties, namely, Catawba, Norton, and Montefiore, 

 selected from the same vineyard during the season of 1909, appeared 

 to show small amounts of sucrose by inversion, ranging from 0.04 per 

 cent in Montefiore to 0.40 per cent in one sample of Catawba. These 

 amounts of sucrose, as shown by reduction with Fehling solution, 

 are too small to denote with any degree of certainty the presence 

 of this sugar, and the Sandusky Laboratory was not equipped with a 

 polariscope for checking the determinations. Sucrose was, however, 

 found in considerable quantities in the well-known varieties Hayes, 

 Worden, and Pocklington, as these were received in the regular work 

 of the laboratory.
