'Then we'd better hurry up, Oswald,' said Herbert Le Breton, 'for guides are the most tyrannical set of people on the entire face of this planet. I shall have another cup of coffee before I go, though, if the guides swear at me roundly in the best Roumansch for it, anyhow.' 'Your acquaintance with the Roumansch dialect being probably limited,' Harry Oswald answered, 'the difference between their swearing and their blessing would doubtless be reduced to a vanishing point. Though I've noticed that swearing is really a form of human speech everywhere readily understanded of the people in spite of all differences of race or language. One touch of nature, you see; and swearing, after all, is extremely natural.' 'Are you ready?' asked Herbert, having tossed off his coffee. 'Yes? Then come along at once. I can feel the guides frowning at us through the partition.' They turned out into the street, with its green-shuttered windows all still closed in the pale grey of early morning, and walked along with the three guides by the high road which leads through rocks and fir-trees up to the beginning of the steep path to the Piz Margatsch. Passing the clear emerald-green waterfall that rushes from under the lower melting end of the Morteratsch glacier, they took at once to the narrow track by the moraine along the edge of the ice, and then to the glacier itself, which is easy enough climbing, as glaciers go, for a good pedestrian. Herbert Le Breton, the older mountaineer of the two, got over the big blocks readily enough; but Harry, less accustomed to Swiss expeditions, lagged and loitered behind a little, and required more assistance from the guides every now and again than his sturdy companion. 'I'm getting rather blown at starting,' Harry called out at last to Herbert, some yards in front of him. 'Do you think the despotic guide would let us sit down and rest a bit if we asked him very prettily?' 'Offer him a cigar first,' Herbert shouted back, 'and then after a short and decent interval, prefer your request humbly in your politest French. The savage potentate always expects to be propitiated by gifts, as a preliminary to answering the petitions of his humble subjects.' 'I see,' Harry said, laughing. 'Supply before grievances, not grievances before supply.' And he halted a moment to light a cigar, and to offer one to each of the two guides who were helping him along on either side. Thus mollified, the senior guide grudgingly allowed ten minutes' halt and a drink of water at the bend by the corner of the glacier. They sat down upon the great translucent sea-green blocks and began talking with the taciturn chief guide. 'Is this glacier dangerous?' Harry asked. 'Dangerous, monsieur? Oh no, not as one counts glaciers. It is very safe. There are seldom accidents.' 'But there have been some?'
