The Berger Bracket for Transit or Level.
This bracket is designed for supporting the instrument under conditions when the
use of even our extension tripod is inadmissible, and will be found a valuable auxiliary
for mining work. The instrument can be screwed upon the bracket, as on a tripod, and
the transit can be centred above or below a given point. The bracket is made of brass,
so fashioned as to offer the greatest rigidity, and is furnished with an auger and a lever.

Short Focus Lens Attachment. (For extended description see page 100.)
The above cut of our wye level and Fig. II illustrate our patented Focus Lens
Attachment, attachable to the object end of the main telescope, which permits the
focusing of objects nearer than the range of the main telescope will permit. As a rule
the main telescope can be made only to focus objects five to six feet distant from
instrument. These lenses are generally furnished in pairs. Lens No. 1 will permit
focusing of objects about 4 feet from instrument. Lens No. 2 will permit focusing of
objects about 2 A- feet from instrument ; used together they permit focusing of objects
about two feet from instrument.
The lenses are adjustable to the line of collimation of the main telescope and permit
of a high degree of accuracy. They will often prove of great convenience as an
auxiliary to view objects that are too near for observing without them. Attachable
to transits Nos. 1, 2, 3, 4, 5, 6, and to our wye and dumpy level.
