2.  Every officer under whom any probationer shall serve during any part of the probation provided for by these rules shall carefully observe the quality and value of the service rendered by such probationer, and shall report to the proper appointing officer in writing the facts observed by him, showing the character and qualifications of such probationer and of the service performed by him; and such reports shall be preserved on file.

3.  Every false statement knowingly made by any person in his application for examination, and every connivance by him at any false statement made in any certificate which may accompany his application, and every deception or fraud practiced by him or by any person in his behalf and with his knowledge to influence his examination, certification, or appointment, shall be regarded as good cause for refusing to certify such person or for the removal or discharge of such person during his probation or thereafter.
