Thus in many argillaceous deposits there are calcareous balls, or spherical concretions, ranged in layers parallel to the general stratification; an arrangement which took place after the shale or marl had been thrown down in successive laminae; for these laminae are often traceable through the concretions, remaining parallel to those of the surrounding unconsolidated rock.
Lastly, denudation, marine and subaerial, has frequently caused the absence of deposits in one basin of corresponding age to those in the other, and this destructive agency has been more than ordinarily effective on account of the loose and unconsolidated nature of the sands and clays. They consist of marls, clays, and limestones of fresh-water, brackish, and marine origin.
The leading crustacean type is the TRILOBITE, which takes its name from the three lobes into which its shell is divided longitudinally. There are also three cross divisions, the head shield, the tail shield, and between the two the thorax, consisting of a number of distinct and unconsolidated segments. The head shield carries a pair of large, crescentic, compound eyes, like those of the insect.
On the waste slopes at the foot of the bordering hills coarse gravels and even bowlders are left, while over the interior the slow-flowing streams at times of flood spread wide sheets of silt. Deep borings show that this great trough is filled to a depth of at least two thousand feet below sea level with recent unconsolidated sands and silts containing logs of wood and fresh- water shells.
Therefore the proper test of expense is the cost of a day's schooling for each pupil, or the cost "per pupil per day." Measured by this standard education in the consolidated school is no more expensive than in the unconsolidated schools; indeed it is usually less expensive.
Proofs of a similar cementing action are seen in a rock at Kelloway, in Wiltshire. A peculiar band of sandy strata belonging to the group called Oolite by geologists may be traced through several counties, the sand being for the most part loose and unconsolidated, but becoming stony near Kelloway.
A thin film of marl, which before it was dried and condensed by pressure must have represented a much thicker layer of soft mud, intervened between the beds of solid gypsum. On this mud the animals had trodden, and made impressions which had penetrated to the gypseous mass below, then evidently unconsolidated.
It is a dissension, an inquiry, it is the vague unconsolidated matter for a new direction.
In Persia, moreover, apart from sporadic outbreaks of persecution in such places as Shíráz, Ábádih, Ardibíl, Iṣfáhán, and in certain districts of Ádhirbayján and Khurásán—outbreaks greatly reduced in number and violence, owing to the marked decline in the fortunes of the erstwhile powerful Shí’ah ecclesiastics—the institutions of a newly-established and as yet unconsolidated Administrative Order were subjected by the civil authorities, in both the capital and the provinces, to restrictions designed to circumscribe their scope, to fetter their freedom and undermine their foundations.
On October 29 White assumed the offensive with the greater part of his command, and endeavoured to cut through the still unconsolidated investing line and to thwart the co-operation of the allies.
