Petroleum springs existed upon the property of the H. P. Co., 
prior to the commencement of their operations. I have been 
told that the a yielded by them was very dense; lower than 
25° Baumé. Upon the property known as the Stanford Oil 
Springs, tunnels are said to have yielded oil of sp. gr. 31° Baumé, 
and a tunnel upon the property of the Wylie Springs OP Co., 
yielded in June last, oil of sp. gr. 23° Baumé. All o f these 
tunnels have been run since July, 1865.

The absence of either very light, or very dense oils, is a 
marked peculiarity of the distillate of Sotithien: California petro- 
leums, when they are treated by direct heat in the ordinary
