Bl'LLETIX 821, U. S. DEPAETMEXT OF AGRICULTUEE. 
In Februaiy the estimated number of frozen fruits picked in the 
Lisbon plat was 54,220. as compared witL 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 ^-ith 29,SS0 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 hare been removed from the trees at 
the first picking. After the April picking there was veiy 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 
Em^eka nonheated plats for the different pickings during the current 
year 1913 are shown in Table XXII.

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 m Xovember, when the percentages are 
nearly uniform. Correspondmgly, the percentage of merchantable 
fruits at each picking is somewhat higher in the Lisbon block than in 
the other.
