The P r e s i d e n t , in m oving th e adoption o f th e R eport o f Council,* said : I regret th a t, ow ing to th e ban on th e printing and distribu tion o f periodicals, th e R eport o f Council has n o t been in your hands before th is m eetin g, and th a t you have n ot been able to stu d y it as you would n orm ally have done.

Copies have been distrib u ted to you th is m orning and I m u st ask you to take it as read.

I t is n o t an u n satisfactory record o f th e a c tiv ities o f the In stitu te, in sp ite o f w h at has been a rather difficult period o f post-w ar adju stm ent— a period w hich is b y n o m eans a t an end, and w h ich I am afraid m a y affect our a ctivities for th e n e x t tw elv e m onths. W e have n o t, perhaps, achieved all th a t w e could h ave w ished, b u t, although th a t m a y be disap pointing, it is no reflection on th e energies and th e zeal o f your Council and s ta ff; th e y have tried their u tm o st and h a v e done noble work. Y ou w ill agree, I am sure, th a t it is alw ays w ell to fix a target rather beyond w h at you hope to achieve, and th a t is w h at w e h ave done.

W e have published during th e year a num ber o f original papers o f great W ednesday, 5 M arch 1947.

m erit, and I am particularly glad th a t our L ocal Sections are all operating again v ery successfully.

Y ou w ould probably like to know th e la te st position w ith regard to the M ond N ickel F ellow ships. T he foundation w as announced tw elve m onths ago, a n d th e legal docum ents have been approved b y all th e five operating societies and b y The M ond N ickel Com pany, L td. The form ality o f signature w ill be com pleted in th e v e ry near futu re, and it ought to be possible in a few w eek s’ tim e to m ake a public announcem ent and in v ite applications for F ellow sh ip s w ith a v iew to awarding a t lea st one or tw o during th e current year.

So far as other m atters are concerned, th e R eport is on norm al lines and speaks for itself.

D r. C. J . S m i t h e l l s , M .C., M.Sc. (Member o f C ou n cil): I beg to second th e m otion. I used to look on th e R eport o f Council as an extraordinarily dull d ocu m en t; i t does n o t really in d icate th e enorm ous am oun t o f work w h ich th e m embers o f th e Council and th e sta ff do. Before I becam e a m ember o f th e Council I had very little respect for th e Annual R eport, b u t I now appreciate th e v a st am oun t o f w ork w hich is carried out.

I should like to draw a tten tio n to one th in g w h ich th e M eetings C om m ittee h a v e done. W e have tried, I hope successfully, to m eet th e w ishes o f the m em bers w ith regard to th e present m eeting. A t th e la st A u tum n M eeting w e held tw o sessions concurrently, in order to be able to deal w ith m ore papers, b u t there w as a feeling on th e part o f m a n y m em bers th a t th e y w ished to be in tw o places a t th e sam e tim e. On th is occasion, therefore, we h ave decided to ta k e only tw o or three papers a t each session, and we are debarring authors from reading their papers or presenting them a t a n y len gth. T his w ill give m uch greater opp ortu nity for discussion. W e in ten d to g iv e each author a t lea st ten m inutes in w hich to rep ly. W e have also added a d a y after the M ay Lecture for more papers. W e w an t to g iv e m em bers an opportunity to discuss every discussable paper w h ich is presented, and w e hope th a t w e h a v e found a solution to th is problem , because there has been a good deal o f criticism in th e p ast.

The m otion w as p u t to th e m eetin g and carried unanim ously.

Re p o e t o f t h e Ho n o r a r y Tr e a s u r e r.

Mr. H . S. T a s k e r , B . A. (Honorary Treasurer) : In subm ittin g the accounts, and m y report * thereon, for th e financial year ended 30 Ju n e 1946, it is n ecessary for m e to m ake on ly a few general rem ark s; I need n o t go in to th e d etails o f th e accounts. There is n oth in g o f great m om ent to w hich to call a tten tio n so far as th e p a st year is concerned, and perhaps th e b est th in g th a t I can do is to read part o f m y report.

(The H on . Treasurer then read th e la st four paragraphs o f h is report, and c o n tin u e d :)

T h at is th e sim plest w a y o f p u ttin g before you th e p osition o f th e In stitu te as it stan d s to-d ay.

v e ry anxiou s th a t m em bers should un derstand th e position , and I h ave pleasure in m oving th e adop tion o f th e accou nts.

Mr. J . C a r t l a n d , M.C., M .Sc. (V ice-P resid e n t): I beg to second th e m otion. I th in k th a t th e p osition is a v ery sa tisfactory one. W e have realized th e situ a tio n for som e tim e, and alth ou gh w e h a v e accum ulated fu n d s there has been an increasing drain on th em as th e facilities are restored for publication. W e an ticip ated th a t th a t w ould be th e case.

I f you look around you , y o u w ill see th a t th e co st o f everyth in g has increased; you w ill find v e r y few th in gs th e co st o f w h ich has n o t gone up b y a t lea st 50 per cen t. T he subscription to th e In stitu te o f M etals is one o f those w h ich has n ot r is e n ; w e are now giv in g th e sam e service— and , in fact, a n im proved service— for a subscription w h ich has been in force since 1920.

W hether w e shall be able to m aintain th a t p o sitio n or n o t is a m atter w h ich th e Council m u st decide.

I should lik e to couple m y seconding o f th is m otion w ith th e proposal o f a v o te o f than k s to th e H on . Treasurer, Mr. Tasker, w ho com bines th e m ost m eticulous a tten tio n to d eta il w ith a broad v iew o f futu re policy.

The P r e s i d e n t : I endorse w h a t Mr. Cartland has said o f th e great debt w h ich w e ow e to Mr. Tasker for th e good w ork w h ich he is doin g in looking after th e financial side o f th e In stitu te . I am glad to see th a t Mr. J o h n F ry, one o f our p a st H on. Treasurers, is here to -d a y . H e w ill appreciate w h at an arduous ta sk it is, especially in th ese tim es o f un certain ty.

The m otion w as p u t to th e m eetin g and carried unanim ously.
