PROPAGATION REVEALED BY THE PLANTING RECORD. 



Another way of judging of the performance of tulip stocks is by a 

 comparison of planting records from year to year. With this, of 

 course, must be coupled the turn-off. It should be noted that it is 

 at planting time that the bulb grower gets a count of his planting 

 stock. He does it by getting a count of the rows planted, as de- 

 scribed elsewhere. 



Table 6 presents a resume of the planting records of the new garden 

 at BeUingham, Wash., for the years 1919 and 1920 for 39 varieties of 

 tulips. It will be seen readily that the computation of a record of 

 yield from a planting of tulips is a complicated affair. It is therefore 

 advisable to present quite a complete record in order that the reader 

 himself may be able to weigh the factors. 



In studying Table 6 it is necessary to compare not only the totals 

 of bulbs planted but also the relation of the sizes. To a degree this 

 is expressed in the weights. To arrive at the complete performance 

 of a variety the turn-off in 1920 and the discard given in the foot- 

 notes, of course, must also be considered. 



In the comparison is given, first, the name of the variety and its 

 class, then five columns headed by figures showing the number of 

 bulbs planted to the row, which are followed by a column for the total 

 of bulbs planted, and finally the weight of the bulbs planted in 1919. 

 The same method of presentation is followed for 1920.
