1. Samples of rice-paste were prepared from the rice grown in the cylinder in open, and the paddy-fields which were devided into the small plots by means of low dykes. 2. The viscosity of both the rice-paste prepared from the polished and unpolished rice, increased with the quantities of the material used, but the inverse is true with their surface tension. 3. The viscosity of unpolished rice-paste was larger and its surface tension was smaller than those of the polished. This difference is due to the presence and absence of rice bran containing a large quantity of fat and electrolyte which have much to do with the viscosity and surface tension. 4. Relations between the viscosity of the unpolished rice-paste and the fertilizer applied were found to be as follows : a.) The composition of fertilizer, giving the largest viscosity. [table] b.) The following relations between viscosity and the compounds of potassium and ammonium so far as their chlorides and sulphates are concerned, were found : The viscosity of rice-paste which came from the plots which received the compounds of the same anion was always smaller than those of different anion, and no different tendency was noticed between the " Uwadai " and the " Shitadai " soils. 5. Relations between the surface tension of the unpolished rice-paste and fertilizer applied, were found to be as follows : a.) The composition of fertilizers, giving the largest surface tension. [table] b.) Relations between the surface tension and the compounds of potassium and ammonium, so far as their chlorides and sulphates are concerned, were as follows : The surface tension of rice-paste from the plots which received the compounds of the some anions was generally larger than those of different anion.
