Narrative

From trees resulting from the planting of a sack of almonds in 1883 A. M. Newland, of Colusa, Calif., selected 69 trees which appeared promising. One of the best of these he named the " Eureka." In 1886 he planted a number of the Eureka trees. Nursery firms soon became interested, and the variety was planted on a small scale in different sections of California. The Eureka, however, was never widely advertised, and inferior seedlings, later called Eureka by others, became more widely scattered than the true Eureka. " Crescent " and " Little Jordan " are other names by which the variety is known. Records of the blooming dates of the Eureka show that it may be useful as a pollinizer of the Nonpareil. The Eureka shell is soft, the kernels are attractive, and the nut though, small has met with favor where known.
