     summary: Moreover, this view does not provide any explanation of the fact that volcanoes are in some way connected with actions which go on on the floors of great water basins. In this condition not only is the excessive flow of surface water diminished, but the moisture which creeps down the slope from the wooded area tends to keep the lower-lying fields in a better state for tillage, and promotes the decay of the underlying rocks, and thus adds to the body and richness of the earth.

     summary: Where there is little water, the surface of the mud hardens and leaves a small opening, through which the bubbling gas throws small columns of mud at regular intervals. One little geyser, known as the Economic, because it throws out but little water, spouts regularly about every five minutes.

     summary: Steenstrup has given to these curious phenomena, many other cases of which occur among the lower animals, and to which he first called attention, the name of alternations of generations. SLEEP OF PLANTS Many flowers close their petals during rain; the advantage of which is that it prevents the honey and pollen from being spoilt or washed away.

     summary: Doubtless the Haidas were intellectually superior to many other tribes, but even if they had not been greatly superior, their surroundings would probably have made them stand relatively high in the scale of civilization. Their beautiful crowns of large white flowers produce a fruit which is one of the mainstays of the Papagos and other Indians of the regions.

     summary: Antonio Ponz (_Viage de España_, i, prólogo, p. lxiii), says: Nor would this be so great an evil, were not some of them declaimers against _trees_, thereby proclaiming themselves, in some sort, enemies of the works of God, who gave us the leafy abode of Paradise to dwell in, where we should be even now sojourning, but for the first sin, which expelled us from it. But the subject is so exceedingly complex and difficult, that it is safer to regard it as a historical problem, or at least as what lawyers call a mixed question of law and fact, than to attempt to decide it upon _à priori_ grounds.

     summary: But a large area in the southwestern part of the state is essentially free from drift, though it is crossed by two belts of valley drift (valley trains) along the Wisconsin and Mississippi rivers. The North American ice sheet._--In an area north of the eastern part of the United States and in another west of Hudson Bay it is believed that ice sheets similar to that which now covers Greenland began to accumulate at the beginning of the glacial period.

     summary: It might, therefore, be held that the early Baltic glacier was separated by no long interval of time from the succeeding great _mer de glace_, but may have been merely a stage in the development of the latter. The ice coming from the Welsh mountains would naturally be deflected towards south-east by the _mer de glace_ that streamed in that direction, and might quite well have carried its characteristic boulders as far as Birmingham before the general _mer de glace_ had attained its greatest dimensions.

The currents of the Mississippi, the Rhone, and of many other large rivers, are modified in the same way.
