In the natural process of growth, the gap must necessarily be wider between the summits of the twigs than lower down, and, instead of imagining " missing links," it is necessary to trace each separate branch as low down as possible, and to institute the comparisons between the lowest points that can be reached.
Farther north in Montana, beyond the gorge of the Missouri river, the structure of the Front Range is altogether different; it is here the carved residual of a great mass of moderately bent Palaeozoic strata, overthrust eastward upon the Mesozoic strata of the plains; instead of exposing the oldest rocks along the axis and the youngest rocks low down on the flanks, the younger rocks of the northern range follow its axis, and the oldest rocks outcrop along its eastern flanks, where they override the much younger strata of the plains; the harder strata, instead of lapping on the mountain flanks in great slab-like masses, as in the Bighorns, form out-facing scarps, which retreat into the mountain interior where they are cut down by outfiowing streams.
The lachrymal foramen in the skull is low down and forms an elongated slit.
Trees to be grown in the form of a bush are usually budded low down on the stem of the stock as near the root as possible to obviate the development of wild suckers later on.
Because the Taffspeed exhaust has so much low down power higher gearing can be used to compensate for more top end speed.
