One eye was fully twice the diameter of the other, and an inch above the horizontal plane of its tiny mate.
It took but an instant, however, for me to regain the levers, and with the roof barely fifty feet above I turned her nose once more into the horizontal plane and headed her again for the black mouth of the shaft.
He arranged the coils carefully in his left hand and the noose in his right, and then he took a position with each foot on one of two branches that lay in about the same horizontal plane and with his back pressed firmly against the stem of the tree.
On these occasions its head is invariably placed downwards; and its wings are expanded in a horizontal plane, instead of being folded vertically, as is commonly the case.
Increasing need for measuring angles in the vertical and horizontal planes has led to an upsurge in demand for surveying applications.

With a need to support the arches in both the vertical and horizontal planes, a critical component of the solution was the design of a special ball joint, with an additional jacking frame system.
Data on voltage (V), current (A), panel temperature ([degree]C), irradiance on the panel and horizontal planes (W [m.sup.-2]) were collected, minute by minute, for a period of one year, beginning on February 1st, 2008.
The paths are arrayed in an "X" pattern in horizontal planes. This orientation enables measurement of swirl, cross-flow and asymmetry, as well as transparent path velocity weighting per the Gauss-Chebyshev profile model for compressible fluids.
Due to the symmetric structure, the reference antennas have the same radiation patterns in both the vertical and horizontal planes. The patterns also remain the same on both ports.
Initial data for solving the this task are diagrams and tables of directivity diagrams in vertical and horizontal planes, data of antenna mounting position.
