K I K-J. K V Through the tho courtesy of the Car Carnegie Car j negle negie Institution the Chronicle isable is isable J. J able to give its readers a illustration il- il t of what a great sun spot c looks like when seen through an immense immense im im- immense mense telescope If U you can imagine a seething boilIng bolling boll boll- ing lug mass vapors on top more or less solid below and great bubbles forming formIng forming form form- ing in that coverlet twisting like mee big whirlwinds around and around or sometimes bursting and shooting spray or vapor up high then you can imagine some of at the aspects of a sun spot Spoken of at too technically will be above the heads of the youngsters so we will avoid that manner of at talking talkIng talking talk talk- ing of at them In this illustration you see a big arc of at a curve marked Edge of J Sun Thru the big telescope the j sun is made to look so much larger C that Instead of at a disc the size of a a I dollar the whole sun would be much much J bigger than a high wagon wheel so only a part of that can be seen at I once so they look at the edge of at the D curve only s Now the boiling inside if It such such you may call It forces up on the edge huge hollow bubbles streaming with forces sprayed up and out like those streamers you see In the ure Flames shoot up boys as high as miles Can you imagine that that Up Up as high as FIFTY TIMES the diameter of the earth And do that in five or six hours Just tr try y to imagine such a force capable o of at yf f that and such speed as that If It LIndy were an airplane e at t that speed hed he'd circle this earth I mighty quick In the illustration the little roun round d ball to one side Is the earth on th the e same size scale the sun edge is shown show n on Note that you could drop th the e entire earth into that bubbling hole with the rays ras shooting out of at it an annot and not touch the edges of the hole halo a at t all Sometimes those flames have actually actually actually ac ac- been been In fact tact the Carnegie Institution sent me u a lantern slide in colors showing Just jus t such a photograph which I have hav e shown to the Boy Day Scouts on a time 3 or two when talking astronomy t to o them This slide sent me shows th the o huge explosion if it that is what It Is propelling the flames and nd clouds o of i gases up 50 times ag alt high as the th e earth bright r red d and such a sight sigh t that it if I could only see it thru a glass glas glassI s I would gaze spell bound at the vas vastness vastness vast vast- t ness of such an act I went over to the scene steno of at a fresh tresh h hs mine explosion explosion- saw mine cars car s blo our hour hundred yards And we w wall ci I blOj all S a agape with thoughts though of at the th e tei to Tf that could hurl an Ir Iron Iron Ir- Ir r on car t t far tar or twist a steel ra ran rail Il like fitter But Dut what of at a force torce to t th o h hu Something FIFTY FUTY T TIMES tES the th e dist e through the earth I have looked at sun spot in Delta a through c a small three Inch glass of at Inexpensive manufacture for tor the tho past fourteen years an and most of the good ones that came along during that I period I have havo seen But I have never nevor nev nev- or er had the tho opportunity to look thru a big telescope When I was at Mt Wilson where the great telescope isas isas is la laas as big as a steel box car the day was misty and besides the public is entertained entertained entertained en en- once a week meek only JOnly and at night times They are too much annoyance an- an annoyance annoyance an an- to have Jumbling things up li- li u so they d ut d nt let em In except onea once one a week a n J 1 then under a guide I would to have seen a bi big sun spot 1 it it with a good illustration illustration tion at han ban and authentic reading matter maUer one ran an n piece it out pretty prelly well at that Ive I've told y j i t boys about calcium and iron sod n m and helium and so forth and r c forth different elements el elements elements el- el their signatures on sun beams so a t wont be necessary I Ito to mention that i l ii w. w Men ren read those J signatures by dying t dying g the Fran- Fran FranJ J lines each element gives on J examination through a spectroscope And by the study of those lines duplicating dup dup- the same elements element's signature under the electric arc When the sun spot is badly boiling o so to speak electrons or tiny little f forces Corces of jump and shoot shootout out Jut as shown by those lines in the And those electro mag letic forces hit the earth and the compass needle begins to wiggle and vibrate and the electric telegraph up around Canada and upper New York gets so bad that the opI op op- orators I cant can't get a through I Static on an the line so to speak That Is on when a particularly particularly particularly furious sun spot is in process of or boiling up And at the same time beautiful Northern lights will appear appear ap ap- pear around the tits polo pale with great streamers shooting out a wondrous sight indeed I have seen some good ones at Delta Farther north better beller bellerand and more often The farther tarther south the more they are lost in the low horizon ho ho- r izon of at the the pole pale tsar The earth is a big magnet and as the electric forces in the sun suti churn things up there liberating berating great impulses Im im- im- im p pulses ulses of at electric energy some of them hit our earth and that extra supply of ot magnetism and electricity set our things topsy jumble us up and raise ruction in to our telegraph key and other things electric Sun spots come in waves of at eleven years our droughts follow tallow those very same waves And tree growth follows drought intervals internals A scientist fist was sent down to Arizona to study sun spots he be got so interested interest interest- ed In studying tree ring growth on the same cycles and putting down the years for sun spots that pretty soon he could cut a a tree off study its rings lugs and tell you the age of the tree and actually point out in the year 1911 that tree suffered from a drought and put out a small thin ring of growth in 1917 it rained like a good fellow and the tree grew a lot lot using the right years as the chart showed I may map not be using the right years but you will wm get the Idea Just as well as if I hunted up the book and gave it right Well Nell he did this back years year BANG DANG One day a n tree in a ruin of the life Ancient Indian gave a series aeries of at i I which matched in tho the chart Lunge DIngo That tree was alive that year I Today that astronomer tells you I Pueblo Donita Bonita was occupied in in 1130 A. A D. D because I a tree a used as a rafter ratter raf- raf ter tor in it had rings that exactly agree agree I with sun spot records dated back to tot I then And the Cliff curt Palace which 1 I have seen dates in 1073 to 1262 I Irom From sun spots to dating Indian ruins From astronomer to treo tree ring student From spectroscope to a agas agas agas gas to fill rm a blimp with non non able able able- wore were ever things so seemingly seeming seeming- ly 11 u unrelated and land yet so Let that suffice for one little talk We started out on sun spots an and d from them found droughts droughts drought s I give trees tices narrow ring growth ring growth is the tue of a tree an and then with further study we find a s tree in the Cliff Palace saying I wa waa was wasa s I a tree cut in 1157 Richard of at the Lion Heart was born that day Thanks boy for reading me thru I Frank Frank Bec Bedkwith |
