  Einstein used 4-dimensional space time geometry to explain gravity. However,
in 1962, Baierlein, Sharp and Wheeler proposed a Jacobi type timeless
Lagrangian based on the 3-dimensional geometry of space to reproduce the same
physics. In 2002, Barbour $et$. $al$. further extended this idea and they call
it 3-space approach. Here we use Bianchi II cosmological model to demonstrate
the 3-space idea. Indeed, we find that this theory is more fundamental and the
manipulation is more practical. We recover the known and find a new solutions.
