This is a convenient point at which to record the subsequent history of the coal deliveries. During the next six months Germany very nearly fulfilled the Spa Agreement, her deliveries towards the 2,000,000 tons per month being 2,055,227 tons in August, 2,008,470 tons in September, 2,288,049 tons in October, 1,912,696 tons in November, 1,791,828 tons in December, and 1,678,675 tons in January 1921. At the end of January 1921 the Spa Agreement lapsed, and since that time Germany has had to continue her coal deliveries without any payment or advance of cash in return for them. To make up for the accumulated deficit under the Spa Agreement, the Reparation Commission called for 2,200,000 tons per month in February and March, and continued to demand this figure in subsequent months. Like so much else, however, this demand was only on paper. Germany was not able to fulfil it, her actual deliveries during the next six months amounting to 1,885,051 tons in February 1921, 1,419,654 tons in March, 1,510,332 tons in April, 1,549,768 tons in May, 1,453,761 tons in June, and 1,399,132 tons in July. And the Reparation Commission, not really wanting the coal, tacitly acquiesced in these quantities. During the first half of 1921 there was, in fact, a remarkable reversal of the situation six months earlier. In spite of the British Coal Strike, France and Belgium, having replenished their stocks and suffering from a depression in the iron and steel trades, were in risk of being glutted with coal. If Germany had complied with the full demands of the Reparation Commission the recipients would not have known what to do with the deliveries. Even as it was, some of the coal received was sold to exporters, and the coal miners of France and Belgium were in danger of short employment. The statistics of the aggregate German output of pit coal are now as follows, exclusive of Alsace–Lorraine, the Saar, and the Palatinate, in million tons: ─────────────────┬──────┬──────┬──────┬──────┬──────┬──────────── │ 1913.│ 1917.│ 1918.│ 1919.│ 1920.│ 1921 (first │ │ │ │ │ │nine months) ─────────────────┼──────┼──────┼──────┼──────┼──────┼──────────── Germany exclusive│ │ │ │ │ │ of Upper Silesia│130.19│111.66│109.54│ 92.76│ 99.66│ 76.06 Germany inclusive│ │ │ │ │ │ of Upper Silesia│173.62│154.41│148.19│117.69│131.35│ 100.60 Per cent of 1913 │ │ │ │ │ │ output │100.00│ 88.90│ 85.40│ 67.80│ 75.70│ 77.20 ─────────────────┴──────┴──────┴──────┴──────┴──────┴──────────── The production of rough lignite (I will not risk controversy by attempting to convert this into its pit–coal equivalent) rose from 87.1 million tons in 1913 to 93.8 in 1919, 111.6 in 1920, and 90.8 in the first three–quarters of 1921.
