EXPERIMENT STATION EEPOPiT. 493 



In the pcheme that follows, the crosses are arranged to the first 

 figure in the combination — that is, all with 5 precede those with a 

 higher initial number. Thus, IX. 5 (6x5) 5 (6x5) indicates that 

 the combinations are as follows : Six was crossed upon 5 — that is, 

 "Scallop" upon "Crookneck" — and the next year after 5 was crossed 

 upon this cross (6x5), giving a three-quarter blood of the "Crook- 

 neck" to one-quarter of the "Scallop," and the present year a cross 

 of the two crosses has been grown as Xo. IX. of the series of crosses. 

 In other words, a cross of "Crookneck" ("Scallop" upon "Crookneek") 

 was bred to its own cross last year, and plants of this combination 

 were grown this season. 



Thirty-three crosses of summer squashes secured in 1903 or 1904 

 were grown the present season. The Eoman numerals stand for the 

 rows which extended across the plot. Each row, of nine hills, was 

 planted with seed from the same fruit, and the nature of the cross is 

 indicated in the second column, and a key to the record figures is 

 given below. Some of the facts obtained as to vines and fruits are 

 condensed into the following tabular form. The record was made 

 early in the season, and therefore upon the first fruits. Later on the 

 number of fruits increased many times, but the fruits of any particular 

 vine do not vary materially :
