12 RECORD OF HORTICULTURE. 



certainly, is a great inducement to plant vines ; but we are 

 assured, farther on, that, when properly planted^ they 

 never suffer from mildew or noxious insects. From this 

 we are led to infer that mildew and injurious insects are 

 known in California ; in fact, the author refers to one case 

 at least, where a friend of his made a complete failure in 

 his attempt to grow grapes. 



Mr. Hyatt makes some prodigious estimates ; but in no 

 instance can we find that the actual results come within 

 fifty per cent, of them. For instance, on page 22, he says 

 " that there are 40,000,000 vines now planted in California, 

 and when tliey sliall all come to the age of, say, three to 

 five years, it may be fairly calculated that they will pro- 

 duce 40,000,000 gallons of wine each year." But if we 

 refer to the report of Col. Haraszthy, on page 76, we find 

 that his vines when five years old only yield three pounds 

 each ; and as it requires fifteen pounds of grapes to make one 

 gallon of wine, it appears that Mr. Hyatt's estimate is just 

 five times too high. Although we are told over and over 

 again in this volume that the grape is a sure crop in Cali- 

 fornia, and that it never fails, still we are constantly 

 reminded that there are great dilfei-ences in soils and loca- 

 tions, some of which are really good, while many others 

 are worthless. Again, on page 20, we are informed that 

 "the grape requires no irrigation in California;" but on 

 page 01, in quoting from an essay of Mr. Flint's, on tlie 

 Division of the Grape Lands of California, we find that he 

 divides them into several districts, and describes the pecu- 

 liarities of each —thus: "First, all that portion south of 

 Monterey County, with the exception of the volcanic range
