A Eureka Lemon Tree Typical of Nonheated Orchards. 
This tre3 shows excessive defoliation caused by the low temperatures and strong winds during the 
winter of 1912-13. A comparison with Plate II shows the relatively greater injury done to Eureka 
than to Lisbon trees in the unprotected orchards. Photographed in January, 1913.
