No people could be better fitted than the Apache to conduct continuous predatory warfare. Every form of plant and animal life pays him tribute. An entirely naked Indian, without implements of any sort, would stop on a mountain slope and in a few minutes be sitting by a cheerful fire preparing a welcome meal. With a fragment of stone he would shape fire-sticks from the dead stalk of a yucca. Sitting with the flattened piece held firmly by his feet, a pinch of sand at the point of contact between the two sticks, with a few deft whirls of the round stick over his improvised hearth the lone traveller would soon have a fire kindled. Into the blaze he would cast a few sections of green, juicy mescal(1) stalk which, when cooked, would afford him both food and drink. This part of his meal finished, the Apache might gather other dead yucca stalks, split them, and often find within small stores of honey. |
It has been assumed in these rules that the titration has yielded proportional results; but these are not always obtained. There can be no doubt that in any actual re-action the proportion between any two re-agents is a fixed one, and that if we double one of these then exactly twice as much of the other will enter into the re-action; but in the working it may very well be that no re-action at all will take place until after a certain excess of one or of both of the re-agents is present. In titrating lead with a chromate of potash solution, for example, it is possible that at the end of the titration a small quantity of the lead may remain unacted on; and it is certain that a small excess of the chromate is present in the solution. So, too, in precipitating a solution of silver with a standard solution of common salt, a point is reached at which a small quantity of each remains in solution; a further addition either of silver or of salt will cause a precipitate, and a similar phenomenon has been observed in precipitating a hydrochloric acid solution of a sulphate with baric chloride. The excess of one or other of the re-agents may be large or small; or, in some cases, they may neutralise each other. Considerations like these emphasise the necessity for uniformity in the mode of working. Whether a process yields proportional results, or not, will be seen from a series of standardisings. Having obtained these, the results should be arranged as in the table, placing the quantities of metal used in the order of weight in the first column, the volumes measured in the second, and the standards calculated in the third. If the results are proportional, these standards will vary more or less, according to the delicacy of the process, but there will be no apparent order in the variation. The average of the standards should then be taken. |

In the evening, while we were sitting at dinner, there was a big bump. We had run aground somewhat heavily on a sand-dune. The captain rather frightened me as he said that on a previous occasion they had stuck on a sand-bank for several days before they could get off. As luck would have it that night, partly by the aid of a steel cable several hundred metres long, which had been fastened to a number of big trees on the shore, partly by her own power, we were able to back out and get her free. Only six hours were wasted. The tide, which reaches a long way up the Tapajoz River when the latter is low, helped us a great deal. At high tide the level of the water is raised more than one foot. It seemed amazing that the tide of the ocean could extend its influence by forcing the water back so far up the Amazon and its tributaries. | ||
