  The equiatomic PrGe single crystal was grown by Czochralski pulling method.
The grown single crystal was found to have CrB-type orthorhombic crystal
structure with the space group \textit{Cmcm} (#63). Transport and magnetization
data reveal large anisotropy in the electrical resistivity, magnetic
susceptibility and magnetization. PrGe was found to exhibit two consecutive
magnetic orderings at 44 K and 41.5 K, respectively. The magnetic
susceptibility measurement along the three principal directions, in low applied
fields, revealed a cusp like behaviour at 44 K while at 41.5 K a ferromagnetic
like increase was observed. The hysteritic behaviour in the magnetization
measurement at 1.8 K confirmed the ferromagnetic nature of PrGe at low
temperatures. The heat capacity data clearly revealed the bulk nature of two
magnetic transitions by the presence of two sharp peaks attaining values
exceeding 40 J/K$\cdot$mol at the respective temperatures. The absence of
Schottky contribution in the magnetic part of heat capacity indicates a
quasi-ninefold degenerate J=4 magnetic ground state in this system. The low
temperature data of electrical resistivity and the magnetic part of heat
capacity show an existence of gap in the spin-wave spectrum.
