The Manganese-Ore Requirements of Germany

Abstract

PROF. CARPENTER, in his article on “Munition Metals” in NATURE of July 15, gives estimates of the resources of the enemy countries in the metals required for war purposes. This information will doubtless prove of great value, especially to those whose duty it is to study the weak points in the armour of our enemies and to devise methods of accentuating those weaknesses; it is consequently desirable that the information so gathered together should be as accurate as possible. In summing up, Prof. Carpenter states that the enemy countries can certainly produce five out of the ten metals considered, without having recourse to imports, these five being iron, manganese, chromium, zinc, lead; whilst he regards it as doubtful whether they can produce from domestic sources sufficient of the remaining five metals—nickel, copper, aluminium, tin, and antimony.
