This statement seems to have started the Californian mind to examining the Californian carobs. The Experiment Station reported that carob beans tested out a little better than barley when mixed with milo and fed to calves for 13 weeks as a grain ration supplementing the milk and alfalfa hay ration fed in addition.^[1]

Mr. C. W. Beers, Horticultural Commissioner at Santa Barbara, went up and down the state studying carob trees. He told me in June, 1917, by letter, that twenty-year-old seedlings, fourteen feet across the tops, had produced one hundred and fifty pounds of beans for three consecutive years.^[2]

per tree. Twenty trees to the acre will thus produce three and a half to five tons each year. He reports grafted trees, eighteen years old, bearing nine hundred to eleven hundred pounds each."

2. C. W. Beers, Horticultural Commissioner, Santa Barbara, June 14, 1917, "The carob trees that are bearing one hundred and fifty pounds each are about twenty years old. They have never had any attention since having been planted and have fought their way in land well grassed over, never having been irrigated. They are about twelve feet to fourteen feet across and about the same in height."

   Letter from Mr. Beers, June 30, 1917:

   "The carob mentioned as bearing one hundred and fifty pounds a year has been very regular in this production for the past three years, which is as long a period as I have been observing them. I believe they can be considered as regularly bearing this quantity.

   "The ground upon which these trees are growing is overlaid with a very heavy deep clay hard pan, which precludes the probability of sub-irrigation. The rainfall is about fourteen inches a year. The land is sloping towards
