In order to protect against and meet emergencies that may arise during each fiscal year, the commissioner shall have the power to set aside a reserve out of each appropriation, the exact amount of which shall be determined by him. Any time during the fiscal year that occasion may require this reserve or any portion of it may be returned to the appropriation to which it belongs, providing the commissioner finds such action necessary.
Whenever it appears to the satisfaction of the Governor that revenues have fallen seriously below those anticipated, the commissioner, on order of the Governor, shall have the power to revise the quarterly allotments.
