It will usually be found expedient to introduce a ring of angle iron around the furnace mouths, though it is discarded in the other parts of the boiler; but it should be used as sparingly as possible, and any that is used should be of the best quality.

Western New York, let him provide himself with angle-worms, and row to the head of the lake.

But their main use was for high-angle fire, such as that from the suburb of St Roch under the walls of Quebec.

Below this indescribable ruin the arid ground sloped down to an artificial water which was surely the lake that the Sultan had made for his boating-parties; and beyond it more red earth stretched away to more walls and gates, with glimpses of abandoned palaces and huge crumbling angle-towers.

Having continued this examination for about half an hour, we proceeded to enter into particulars respecting triangles; and having discoursed on the difference between isosceles triangles and scalene triangles, I observed that an acute isosceles triangle had all its angles acute, and proceeded to observe that a right-angled scalene triangle had all its angles acute.

My angle-rod is broke, my sport is done, But I will fetch my net to catch some fish; To lose both fish and pleasure is too much.

In both Singer's and Wheeler & Wilson's latest styles of machines this arrangement is simplified and improved by the use of a single angle clutch, which is found to work even when the surfaces are freely oiled (Fig. 6).

All around are the outer lines of ramparts, walls beyond walls, their crenellations climbing the heights, their angle fortresses dominating the precipices.

The aeroplane was greeted by a storm of shrapnel from the high-angle guns mounted on the fortifications, the only effect of which, however, was to kill two unoffending citizens who were standing in the streets and were struck by the fragments of the falling shells.

In these geometries the sum of the angles of a triangle is not two right angles, and the departure from two right angles increases as the size of the triangle increases.

For a angle instant, the young commander paused with big hand on the door of the cabin, and then, overcoming his reluctance, he entered the apartment.

Each face of the tower is divided, apart from the narrow angle buttresses, into six vertical divisions separated by thin projections of buttress form.

The greatest length lies east and west, in a line with the Wall; and two broad streets crossing each other at right angles lead from the north to the south, and from the east to the western gateways.

You cannot focus on details when using a wide-angle lens in your camera.

That is, the angle of deflection would be a o a′, double the angle p

EP is the normal, and the actual motion of P is PM, perpendicular to EP, the angle PEM being made equal to CEA.

The fuller development at St. John's of the peculiar treatment of the angles points to its being a little later

"Occasionally, with a roar, a high angle projectile would sail over the hill and blast a gap in the village.

The deck over the steam chest should be formed of an iron plate supported by angle iron beams, and there should be a high angle iron cooming round the hole in the deck through which the chimney ascends, to prevent any water upon the deck from leaking down upon the boiler.

The upper two-thirds of the spire has triple angle rolls, and, just halfway in the total height, are eight canopied panels of which four are pierced.

The inner one, with a finely moulded arch with angle shafts and the vault with simple diagonal ribs carried on shafts, is of the early thirteenth century.

Then from behind her came the hoot of a motor-horn, and she glanced back to see a closed car that glittered at every angle swoop through the open gates and swerve round to the churchyard.

Later, when it became clear that the rebels could not be dislodged from this stronghold by street rushes, no attempt was made to shell them out of their strong position by a high-angle bombardment of plunging explosive shells.

It should have a good prism eyepiece with an angle tube attached so it would not be necessary to break one's neck in reading high altitudes.
