Nazario e Celso), a small structure in the form of a Latin cross with a dome (in which, as in the baptistery of Neon, the old cathedral, &c., the constructional use of amphorae is noteworthy), with a plain brick exterior, and rich mosaics on a dark blue ground within.
The result is that the tracery itself has to support the structure above it - is, in fact, constructional - whereas in most other countries the tracery is merely, as it were, a pierced screen filling in a constructional arch.
The Conway quarries, four in number in 1908, are on either side of the Saco river, south-east and south-west of North Conway; their output is coarse constructional stones, all biotite or biotite-hornblende, but varying in colour, pinkish (" red ") and dark-yellow greenish-grey (" green ") varieties being found remarkably near each other at Redstone, on the east side of the Saco valley.
The surface soil is clay in which are embedded fragments of siliceous sandstone, used for millstones and constructional purposes; the subsoil is limestone.
The constructional choir is often wanting, the whole church forming one uninterrupted structure, with a continuous range of windows.
On the other hand, grammatical and constructional examples may be cited from other more modern agglutinative idioms, in order to establish the truly linguistic character of the Sumerian peculiarities and to disprove the Halevyan contentions that Sumerian is really not a language at a11.4 It is not surprising that Halevy's view as to the cryptographic nature of Sumerian should have arisen.
- This class includes most of the soft woods which furnish timber for the framing and constructional portions of nearly all building work.
No medullary rays are visible; the wood is straight in the grain, durable, strong and elastic, easy to work, and is used by the carpenter for internal and external constructional work, and by the joiner for his fittings.
The wood when cut is white or yellowish white, straight in grain and easily worked, but is not so tough, elastic or durable as the northern pine, and therefore is not so suitable for constructional work.
Its weight and strength, and the large size of the balks, make it very valuable for heavy constructional works and piling, and its fine figure makes it equally valuable for joinery.
Their initial expense and the high cost of working preclude their general use, and they are consequently reserved to a great extent for specially heavy constructional work and ornamental finishing joinery.
It is very suitable for constructional and engineering works, and it supplies one of the finest woods for ornamental joinery work.
In some European and other countries, however, the safe working stresses of timber used for constructional purposes are defined.
One of the most difficult problems with which the metal-worker who handles constructional forms has to deal is the maintenance of a due relation between absolute strength and a useful degree of elasticity.
Severe simplicity is also most in harmony with constructional designs in plated work, where stresses occur in straight lines.
