378 Field Museum of Natural History — Reports, Vol. V. 



This bridge has been completed and has greatly increased the means of 

 access to the Museimi. 



The scope of the Stanley Field Museum Employes Pension Fund 

 has been enlarged by its founder, the execution of an insurance contract 

 with the Aetna Insurance Company covering the lives of the personnel 

 of the Museum, with the premiimi paid out of this Ftmd, having been 

 authorized. In this contract it is stipulated that continuous service for 

 one complete year is pre-requisite to securing any insurance and that 

 the insurance automatically ceases upon the termination of the services 

 of the insured. Employes, who on February i, 1920, had not been in 

 the service of the Museimi for one complete year, automatically become 

 insured at the conclusion of that period, and are progressively entitled 

 to increasing benefits as set forth in the schedule adopted. This insur- 

 ance is without cost to the insured and imposes no obligation not already 

 attending the services of the employe. 



Maintenance. — ^The sum of $170,200.00 was appropriated by the 

 Board of Trustees for the necessary expenses of maintenance during 

 the fiscal year. The cost of maintenance, however, amoimted to 

 approximately $190,000.00, thus creating a deficit of approximately 

 $20,000, which, as referred to elsewhere in this report, was contributed 

 by Mr. Marshall Field. 



MOVING Operations. — The following is a brief simimary of the 

 extent and cost of the transfer of all collections, material and equipment 

 from the old building in Jackson Park to the new building in Grant
