places. These soils are common over the Livermore Valley and pro- 
duce a superior white wine of the sauterne type. This experiment 
vineyard was discontinued on July 1, 1914. 
LODI EXPERIMENT VINEYARD. 
The Lodi Experiment Vineyard was established in the spring of 
1904, on the Lawrence & Murray property, about one-fourth of a 
mile northeast of Lodi, San Joaquin Co., CaL, about 55 feet above 
sea level. (See PL III, fig. 3.) A large body of this soil exists 
between Lodi and Acampo. 
There are two variations on the plat. Phase No. 1 is a brown, free, 
sandy loam, underlain below 4^ feet by a more adhesive light-brown 
or yellowish sandy loam. Occasional iron concretions give the sub- 
soil a mottled color. The soil has good capillarity and the water 
table occurs at 5 to 6 feet. Phase No. 2, an adhesive sand, was 
formed by an old stream channel. This is light-brown sand to a 
depth of 3 feet, the subsoil water-washed sand, much looser in tex- 
ture and lighter in color, and dry to a depth of more than 6 feet, as 
the soil texture is too loose to exert much capillary force. There 
is no hardpan or alkali. The soils are, however, deficient in lime; 
otherwise, they are very productive, comparatively level, unirri- 
gated, and easily tilled. This locality is well known for its table 
grapes and as a table-grape shipping point. 
MOUNTAIN VIEW EXPERIMENT VINEYARD. 
The Mountain View Experiment Vineyard was established in the 
spring of 1904, on the property of Mrs. Caroline Distel, 2 miles west 
of Mountain View, on the west side of the Santa Clara Valley, 76 feet 
above sea level. (See PL IV, fig. 1.) 
The soil is a gravelly Placentia sandy loam. The first 12 inches 
is a dark-brown, gravelly sandy loam, dark from humus; below this, 
to 4 feet, the subsoil becomes redder, sandier, and more gravelly 
until sand is encountered. It is well drained, but inclined to become 
too dry in summer and fall. The surface soil at times becomes quite 
compact, and when plowed breaks up into hard clods. When tilled 
at the right time it works into a very mellow condition. These soils 
are from washings of granitic sandy shales and schist rocks. Before 
the destruction of vineyards by phylloxera and other agencies the 
Santa Clara Valley was the banner dry-wine producing section of 
California. The following areas of Placentia sandy loam have been 
surveyed in California: San Jose, 61,500; lower Salinas, 74,000; Los 
Angeles, 66,000; San Bernardino, 87,000; San Gabriel, 48,800; and 
Santa Ana, 16,800 acres. Soils of this series occur through the coast 
range of mountains from San Francisco to the Mexican line, occupy- 
ing undulating portions of valleys close to the hills. The Mountain 
View Experiment Vineyard was discontinued on July 1, 1912.
