It is hardly possible to insist on a greatly increased productivity of German industry if the workmen are to be underfed.

But this may not be equally true of barley, coffee, eggs, and tobacco.

If it were possible to enforce a regime in which for the future no German drank beer or coffee, or smoked any tobacco, a substantial saving could be effected.

Otherwise there seems little room for any significant reduction.
The following analysis of German exports and imports, according to destination and origin, is also relevant.

From this it appears that of Germany's exports in 1913, 18 per cent went to the British Empire, 17 per cent to France, Italy, and Belgium, 10 per cent to Russia and Roumania, and 7 per cent to the United States; that is to say, more than half of the exports found their market in the countries of the Entente nations.
