the foliage. Another vineyard close by was also found to be slightly 

 affected. This was on somewhat higher ground. 



At Vista, some 10 miles distant from the above vineyards, and about 

 14 miles from Escondido town, a series of low hills and small valleys 

 intervening, the Anaheim disease was also found. The vines were in 

 good, deep soil, and generally were strong and healthy, and were well 

 supplied with natural moisture. The varieties were Mission, Mataro. 

 Muscat, Riesling, Black Hamburg, and Black Morocco. The fruit was 

 all used for wine making. Here the disease was of older standing, 

 some vines having been affected last year. Some of these were dead ; 

 others had put out only the usual stunted growth. In this vineyard 

 the disease had appeared in small patches rather than in single vines. 

 The greater number of sick vines w r ere in one corner of the vineyard, 

 where the soil was more adobe than anything else. The owner asserted 

 that he had vines which had been diseased, but which had quite recov- 

 ered. 



In the Escondido Valley proper the vineyards, which are almost all 

 set out to raisin grapes, were found to be in excellent condition. Nothing 

 w r as found to be the matter with the vines, except that in a few spots they 

 showed slightly the effects of want of moisture, due to the short rain- 

 fall of last winter. Besides this, there was a small plot of Mataro 

 vines which had been somewhat badly mildewed. This was on a hill- 

 side some distance away from most of the vineyards. Besides this, 

 no other sign of sickness was found, The vines all over the valley had 

 made a good growth, and had borne a fair crop of fruit, which was of 

 excellent quality. Drying was still going on at all the vineyards, the 

 cool season having delayed this operation. 



In the adjoining districts of San Marcos and Twin Oaks the vines 

 were extremely vigorous, the fruit being of large size and good quality. 

 No Anaheim disease was found here, nor did there seem to be any other 

 trouble present. 



In El Cajon Valley the vines were also in good condition. In some 

 places, where the vines had not been irrigated, they showed some effects 

 of the short rainfall, but no Anaheim disease was found. It will be 

 remembered that it was in this valley that the first outbreak of Ana- 

 heim disease was reported in 1889. A special visit was made to the 

 two vineyards then affected. The vines are now perfectly healthy, and 

 show no sign of sickness, and have borne good crops all along. This is 

 an extremely satisfactory state of things. 



In the Sweetwater Valley the vines are also in excellent condition. 

 As in other places, those vines on lighter and poorer soils showed the 

 effects of want of water, but this was the most serious thing the matter. 

 Here and there in the valley there were patches of vines having their 

 leaves spotted in a manner very similar to the markings produced by 

 the Anaheim disease; but that these vines are not affected by the 

 Anaheim disease is evident for various reasons. The markings on the 

 leaf are not the same as those brought about by the Anaheim disease, 

 though they are much like them. The number of vines affected varies 

 from year to year; sometimes very few are found, sometimes more, 

 especially in a dry season. The vines do not die, nor become stunted, 

 but put out their normal growth, and bear a good crop every year. 

 Frequently the spotted leaves remain on the vine just as long as those 

 not so affected. The fruit is not affected in any way, either in quantity
