  The Horndeski theories are extended into the Lovelock gravity theory. When
the canonical scalar field is uniquely kinetically coupled to the Lovelock
tensors, it is named after Lovelock scalar field. The Lovelock scalar field
model is a subclass of the new Horndeski theories. A most attractive feature of
the Lovelock scalar field is its equation of motion is second order. So it is
free of ghosts. We study the cosmology of Lovelock scalar field in the
background of $7$ dimensional spacetime and present a class of cosmic
solutions. These solutions reveal the physics of the scalar field is rather
rich and merit further study.
