Take two ounces of sal ammoniac, one ounce of flowers of sulphur, and sixteen ounces of cast iron filings or borings.
borings in the delta of the Mississippi show soils and remains of trees at many levels, alternating with river silts.
Care should be taken to avoid and eliminate all borings and chips from the sample.
The pest is easily discovered through the exudation from the infested part of gum mixed with borings and excreta.
borings at different places show the fen soil to vary in depth from 24ft.
borings to great depths have been made in various parts of the earth, both for artesian wells as well as for the shafts of mines.
Ninety-five of these borings were made in various places, but on no occasion was solid rock reached.
Henriksen has for the most part made these borings, and is a trustworthy man for this work.
But it is not often that borings come to be made in river alluvia.
It will therefore be necessary to employ the greatest care before proceeding with any borings.
