ONE:There the German authorities detained me for a full week, by prohibiting me to return: "for the sake of your own safety," they told me courteously. During the day I was busy enough, and in the evenings I enjoyed the pleasant company of the three fathers of the Sacred Heart who had remained in the137 mission house, and with whose photographic instrument I took many a snapshot of the Louvain ruins.
TWO:It would be inferred that the arrangement of these double acting hammers must necessarily be complicated and expensive, but the contrary is the fact. The rams are simply two masses of iron mounted on wheels that run on ways, like a truck, and the impact of the hammers, so far as not absorbed in the work, is [114] neutralised by each other. No shock or jar is communicated to framing or foundations as in the case of single acting hammers that have fixed anvils. The same rule applies in the back stroke of the hammers as the links which move them are connected together at the centre, where the power is applied at right angles to the line of the hammer movement. The links connecting the two hammers constitute, in effect, a toggle joint, the steam piston being attached where they meet in the centre.
