II. Lysimeter Water. 



Lysimeter water is atmospheric water passed by means of suit- 

 able apparatus (Lysimeter) through different soils, and collected 

 after passing through. (See pp. 99, 100.) 



The chemical analyses embraced four series, and were made by 

 Dr. Zoeller. 



1. Series of analyses made in 1857. 



The experiments were made with five different soils, 1 square 

 foot of each earth, 6 inches deep, being placed in the several 

 lysimeters. The quantities given represent the amount of 

 atmospheric water that passed through the several lysimeters 

 from April T to October V, 185T. I. Manured calcareous soil, 

 with vegetation (barley). II. Unmanured clay soil, with vege- 

 tation. III. Unmanured clay soil, without vegetation. IV. 

 Manured clay soil, without vegetation. Y. Manured clay soil, 

 with vegetation. (2 Ibs. cattle-dung, without straw, were sev- 

 erally used to manure the earth in lysimeters I., IV., and V. 



* a. Drainage water from land A (a clay soil resting on a subsoil of cal- 

 careous loam or clay), collected 1st April, 1853. b. The same, collected 1st 

 May, 1853, after a heavy fall of rain (218 cubic inches on the square foot). 

 c. Drainage water from the same soil, mixed with drainage water from a 

 humous clay soil, with calcareous clay or loam as subsoil, collected in Octo- 

 ber, 1853. d. Drainage water from land B (tile-drained; subsoil of calcare- 

 ous clay or loam), collected in October, 1853. e. Water passing through the 

 water-furrows from a heavy clay soil, collected in the beginning of June. 

 f. The same, collected in the middle of August, after heavy rains.
