BULLETIN 821, U. S. DEPAETMENT OF AGRICULTUKE. 



In February the estimated number of frozen fruits picked in tbe 

 Lisbon plat was 54,220, as compared with 99,510 in the Eureka or- 

 chard. On account of the open habit of growth of the Eureka tree a 

 larger number of mature or nearly mature lemons were frozen in this 

 variety than in the Lisbon. In the April picking, however, the esti- 

 mated number of frozen fruits in the Lisbon plat was 72,640, as com- 

 pared with 29,880 in the Eureka. The greater number of frozen 

 lemons at this picking in the Lisbon orchard, as compared with the 

 preceding one, was probably caused by the fact that the dense char- 

 acter of growth of the Lisbon trees in this particular orchard hid 

 many of the fruits which should have been removed from the trees at 

 the first picking. After the April picking there was very little dif- 

 ference in the number of frozen fruits produced in each orchard. 

 Both orchards returned to normal production about the last of the 

 year. In the case of the merchantable fruits, however, the Lisbon 

 plat at each picking bore a greater number of sound, merchantable 

 lemons than the Eureka. 



The percentages of fruits by the different grades in the Lisbon and 

 Eureka nonheated plats for the different pickings during the current 

 year 1913 are shown in Table XXII. 



Table XXII. — Percentages of fruits by grades produced on the nonheated acre of Lisbon 

 lemon trees, plat 2, as compared with the nonheated acre, plat 3, of EureJca lemon trees, 

 during the calendar year 1913. 



[These percentages are computed from the total number of lemons produced hy these plats, as sho'wn in 



Tables VI and VII.]

A graphic presentation of the percentages of frozen and merchanta- 

 ble fruits in the Eureka and Lisbon nonheated plats is made in figure 15. 

 The percentage of frozen lemons at each picking in the Eureka plat 

 is somewhat higher than the percentage of frozen ones in the Lisbon 

 plat until the last pickings in November, when the percentages are 

 nearly uniform. Correspondingly, the percentage of merchantable 

 fruits at each picking is somewhat higher in the Lisbon block than in 

 the other.
