from the patient all that he or she can tell about the friends and 

 relatives, especially with reference to their addresses, etc. The patients 

 enjoy these visits, and are often able to give very useful information. 



Everything now being ready for the visit to the home, the field 

 worker, armed with recent personal knowledge of the patient, which 

 assures her cordial welcome, visits the home and interviews the rela- 

 tives, friends and family physician. To secure satisfactory results, 

 sympathetic and confidential relations must always be maintained. It 

 is better to leave some details to another visit than to have relations 

 at all strained. The field worker's constant endeavor must be to 

 establish a feeling between the family and Institution that will assure 

 her of a welcome at any time with kindly cooperation, and to this end 

 she sacrifices minor details that would naturally come on return visits. 

 The field worker endeavors to see as many relatives as possible. In 

 this way facts omitted or overlooked by one are often recalled and told 

 in full detail by another, and by this means information already 

 obtained is confirmed. Every additional interview is sure to reveal 

 new facts. 



Addresses of relatives who live in other sections are recorded 

 to be used later by an investigator in that section. References to foreign 

 countries are also kept, with the town, and wherever possible, the 

 street address. In the case of foreign born parents, an endeavor is 

 made to obtain data relative to the time of immigration, the town 

 from which they came, and other information that may be useful. 



Whenever the field worker learns of any defectives who need 

 Institutional care, their names and addresses are obtained, and filed 

 with the other material. By this means useful information is available 

 when application is made for admission to Institutions. 



As collected, the data are carefully recorded, and the pedigree 

 chart made of the family. This is then put in permanent form on a 

 sheet of white paper 8 x 101/2 inches, with such notes and symbols as 

 have been adopted to designate certain traits. A full description, with 

 all details, is typewritten and filed with the chart. 



2. THE CHART (Plate I). 



The plan of charting adopted is based on the decisions of a com- 

 mittee of the American Association for the Study of the Feeble- 

 Minded held at Lincoln, Illinois, in 1910. This committee consisted 

 of Supt. E. R. Johnstone and Dr. H. H. Goddard, of Vineland,
