Description | Describes the definition of 'indispensibility' and his own position as an official agricultural analyst, a role which he says requires many years of experience -- notes that there has been 'a great exodus of young chemists to the war', and others are pressured to enlist -- thinks that there should be some ruling which could render indispensible workers 'immune from reproach' and some sort of badge to make their position clear -- comments on the urgent need for more analysts and does not think work can continue unless something is done. |
