No. 20 — Han ford Fine Sandy Loam 



Location : Near Hopeton, Merced County, 14 miles north of Merced. Less than 

 y± mile north from the road corners, 15 feet east of the east fence of the 

 road, and 150 feet south of irrigating ditch. 



Soil: A good medium brown fine sandy loam. The color is especially good when 

 the soil is moist. The topography is slightly uneven because of the old 

 stream channels. Going north along the road from the cross roads the 

 soil is quite gravelly at first, but the texture gradually becomes heavier, 

 with less gravel. At the sample station the texture is a rather heavy fine 

 sandy loam. 



History: J. G. Euddle, Snelling, owner. The field is planted to alfalfa, as are 

 most of the Hanford soils in the locality. The land is not subject to 

 overflow. Sample collected April 13, 1916. 



Depths of horizons: 



20-A 0-12 inches. 20-B 12-24 inches. 20-C 24-36 inches. 



No. 21 — San Joaquin Sandy Loam 



Location : Near Nairn Station, Merced County. About % mile west of the rail- 

 road, 50 feet north of the private ranch road, and 120 feet east of the field 

 gate across the road. About 4 miles northwest of Merced. 



Soil: A good brownish red San Joaquin color. Texture a sandy loam, grading 

 into a clay loam or clay at about 24 inches. 



Depths of horizons: 



24-27 inches — A heavy clay. 

 27 inches — Hardpan. 



The same was taken from near the top of one of the hog wallow elevations. 

 The topography is gently rolling. 



History: F. W. Henderson, Merced, owner. At the present time the land is used 

 as pasture. It has been plowed at some time in the past. The present 

 growth of wild herbage (Lepidium, small grasses, Cryptanthe, etc.) is 

 meager. Sample collected April 13, 1916. 



Depths of horizons: 



21-A 0-12 inches. 21-B 12-24 inches. 21-C 24-27 inches. 



No. 22 — Hanford Fine Sandy Loam 



Location: A short distance north of Basset, Los Angeles County, on the main 

 road north from Basset station. The sample was collected in a walnut 

 grove 100 feet east of the road and 250 feet south of the driveway to the 

 ranch house. 



Soil: A good medium brown when moist, and a light grayish brown when dry. 

 Mr. L. C. Holmes, of the U. S. Bureau of Soils, described the soil at the 

 time of collection as being "all a little browner, and with a little more 

 color than a good Hanford." There was a very slight color change at 

 about a foot, the soil below was grayer. Texture a good fine sandy loam, 

 with practically no change in the 3 foot column. Topography smooth. 

 The texture varies quite rapidly from place to place in the field. Some 

 big washes of typical intermittent streams are found not far to the north 

 and west.
