A point of discharge complying with these conditions cannot always be found to exist close to the town, or requires to be ascertained by careful tidal and other observations. At the outfall there should be a continuous movement seaward during the twenty-four hours, instead of an oscillating action to and fro, resulting...

In no instance is the ammonia absorbed by soils from solutions of free ammonia, or from salts of ammonia, so completely or permanently fixed as to prevent water from washing out appreciable quantities of ammonia. 8. The proportion of ammonia which is removed in the several washings is small in proportion to that retained by the soil. 9. The power of soils to absorb ammonia from...
