1.  Every original appointment or employment in said classified service shall be for the probationary period of six months, at the end of which time, if the conduct and capacity of the person appointed have been found satisfactory, the probationer shall be absolutely appointed or employed, but otherwise be deemed out of the service.

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 report 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 the removal or discharge of such person during his probation or thereafter.

  RULE XXI.

1.  No person, unless excepted under Rule XIX, shall be admitted into the classified civil service from any place not within said service without an examination and certification under the rules; nor shall any person who has passed only a limited examination under clause 4 of Rule VII for the lower classes or grades in the departmental or customs service be appointed, or be promoted within two years after appointment, to any position giving a salary of $1,000 or upward without first passing an examination under clause I of said rule; and such examination shall not be allowed within the first year after appointment.

2.  But a person who has passed the examination under said clause I and has accepted a position giving a salary of $900 or less shall have the same right of promotion as if originally appointed to a position giving a salary of $1,000 or more.

3.  The Commission may at any time certify for a $900 or any lower place in the classified service any person upon the register who has passed the examination under clause I of Rule VII, if such person does not object before such certification is made.

  RULE XXII.

Any person who has been in the classified departmental service for one year or more immediately previous may, when the needs of the service require it, be transferred or appointed to any other place therein upon producing a certificate from the Civil Service Commission that such person has passed at the required grade one or more examinations which are together equal to that necessary for original entrance to the place which would be secured by the transfer or appointment.
