Dr John C Calhoun has spent a year observing mice awake and asleep at work and at play in "Mouse City" This is a research project he has set up in the Jackson Memorial Laboratory here And although he makes no comparison between man and mouse he has found that under certain conditions the behavior of mice gives him an idea of what to expect from mortals Whether you do or don't live in an apartment house you should be interested in Dr Calhoun's experiments At "Mouse City" he built apartments for families of both ' aggressive and mice Then he sat back and'watched them as they sought the everyday needs of mice and men: food water and a place to live What has he found? In the first place he has discovered that mice develop different degrees of tolerance toward each other — de pending on the genetic strain I1 m le - Ilk i BAR HARBOR How - :: '' - ' z4 ilims: A7:- Lo- : 9 A1 1 - 4 0 sTegor i--34$ : : E7164:16 iiis ' 'Urban nlice'al(lstotly of mankind ' 1 Tr T :!le i Itr' - ----' : - - ' 1 7) tI -- ' p4 lkor 45 ' :: I i '' 1: - o '- -' ' r use ' 1 oill 4 r - -- - - -- 'I -- ' t 'f ' I 4' ''' li e f' ' - -a--- - — - i ::: -- ----0 v 4fffi i : '''tr?'r'''0-!1:':'- rt 1 - ' ' 1 ! - c r 1 0 "' t''-- -- c74 1 fr ' Al It INSPICT011 NI3j0f Ralph O Heat ley is Air 'wipes-to- r Seinen Air Deferuse Frove An Aviation Cadet in '41 he is now in the regular US Air Forte SALIS George Sperry WNW PKOT Charles MacDonald is 11461NE 11 Vies males engineer Gyroarope Co- - la a former Aviation Cadet Served aa commercial pilot then ioined Sperry in '40 (lief of Combat Ae 'Awed S Air force ore making These Airmen of the the insure to help observations and instrument weother When crews and Force pilots Air of solely and success their aptitude the Air Force tests showed they first joined in on Air Force trained were for this career fiekl They important in weather work school apd assigned to mighty Air force the of supporting the fighting pacts U S Air force fits the The too kfe impedeIt in civilian career fields in the U S Airman to his job There are 47 for you as on Airman loa Air force There is a career L VilJo Jo n k ao01111 011311$ be 400 i A of nt 4 Got ea Top Stay on Tool flood the tocts it this &whist's(' booklot now essztlobtoI at your newest U S Amy oast U S Alt Force itostvitsse Shelton or of ny U S Ai Force Soso ----:-- TO01 U IDLICUITItt Paerfie-Alaak- Continental Air Command A am be trained first as an Aviation Cadet -- EGray a the thyiaion Pan American World Airways t4ystem also started out aa an Avitition Cadet ipecauons r-- OPPORTUNITIES AS AIRMEN MALMO H UNNI 0 (ft 4 -- - 1' 4 4414: vise row Brio SO U sonweet 0 tir" Irtaco:turn :4'912411 Ab ( POPIO S Army moil U S Ab Pomo tomolliibe SWAN- - :a (77) LsU NOvfmatit 26 1950 ipatodo 23 |
