The depth of this gutter should be about the same as the traps; 

 hence, if the traps are set into the floor two inches, this gutter 

 should be about two inches deep. 



Cesspool. 



If there is a gravel bed near where the creamery is built, 

 this may be utilized for disposing of the sewerage, and it is often 

 possible to get very satisfactory drainage by digging a large 

 hole in the gravel and running the sewerage into it. It will, of 

 course, be necessary to curb up such a hole with some kind of 

 material, in order to keep it from caving in. The hole should 

 then be tightly covered on top to prevent odors from escaping. 

 If such a hole should fill up in time, a new" one can be dug at 

 a small expense, but it might be still better to dig two holes at 

 the start letting the sewerage flow from one into the other some 

 distance from the bottom. In that way most of the solid mat- 

 ter would be . precipitated in the first hole, and this could be 

 cleaned once in a while if necessary. But after all it is much 

 more satisfactory to spend considerable money for a long drain 

 when such is possible. 



When a cess-pool is built it should be at least 75 to 100 feet 

 from the well, and further if possible. If the cess-pool is located 

 too near the well, there is always danger of polluting the water, 

 and very serious results might follow. 



Septic Tanks. 



The septic tank, as a means of disposing of creamery sew- 

 age, is yet to a certain degree in the experimental stage, and 

 it is not advisable for a creamery to install a septic tank unless 

 they have no other way of taking care of their sewerage. The 

 strange thing about septic tanks is that they work well in some 

 places, while in other places they do not; though this would in- 

 dicate that the tank itself is not to blame, but it may be due to 

 the different methods employed in handling them. 



It is true that in a number of instances the septic tank has 

 been built altogether too small and it will easily be understood
