New York Agricultural Experiment Station. 109 
The indications are very clearly that the soluble matters contained 
in the water from the muck, and the garden soil promoted the capil- 
lary flow, but that some quality of the manure water retarded it. The 
latter was passed through filter paper before being used, but may still 
have contained viscous material that tended to clog the pores of the 
soil. In another experiment with vertical tubes, one of which was 
connected with manure water and the other with distilled water, the 
manure water again fell behind. 
The next trial was intended to discover whether or not the rate of 
capillary flow may be promoted by the addition of any special sub- 
stance to the water. The first test was with sodium chloride (common 
salt). A comparatively pure article of dairy salt was used, and solu- 
tions of twenty, ten, five and two and a half per cent respectively 
were connected with the horizontal tubes, as described in the last 
experiment.
