1. Reference is made to secret letter. your headquarters. 
dated 
1 April 1949• Subjects Security Inspection. 
2. a. Guard Orders have been amended directing that the elec­
tric gate be closed between 1700 hours until 0700 hours the following
day. 
b. Looks have repl~ced the bolts in all inspection access 
gates in the outer fence. 
c. Inspection ports on both bridges are now pr ovided with 
locks. 
d. The final draft of our alert plan has been reviewed and 
will be published and distributed for study to operating personnel. 
It is desired to point out that the alert plan is incomplete. !. 
stockpile custodian has not been assigned here; his part in the alert 
plan has been outlined only. Furthermore, since the 11th Airborne 
' 
Division is not in place yet, only temporary arrangements for defense 
have been made. Final form of the overall alert plan will be sub­
mitted to your headquarters for approval as soon as conditions will 
allow. ·1n the interim period. it is felt that the temporary alert 
plan we have prepared is adequate. A copy of this pl an will be dis­
patched to your headquarters in the near future. 
e. !11 jeep radios are now installed in jeeps. 
r. ~lthough not entirely satisfactory. radio oom.munioation 
with the Camp Campbell Military Police has been in effect for some-
time and was in effect at the time of the Security inspection. .Pe~­
manent a
rrangements for radio communication with Camp Campbell Military 
Police are delayed panding the arrival of radio frequency crystals 
that fit the Milit ary Police net frequency.

SUBJECTs Security Inspection 
g. Pressure has been exerted to get the Pos t 'Ehgineers to 
keep the dra.inage system. clear and to take measures to check the ero­
sion. These efforts will be continued but little progress on erosion 
control can b e expected until the rains diminish. Ditches have been 
filled, dirt moved and replaced, native grasses planted, but the rains 
return too soon and much of the effort invested is therefore wasted. 
Plans a.re prepared f or an interim erosin control effort, and a stud;y 
is being ma.de to estinate the cost of resloping the cuts in order 
that the rainfall mq be drained with less damaging results. Initial 
estimates run in the neig hborhood of twenty thousand dollars (t20,ooo.oo). 
3. With the exception of halting the erosixm, all deficiencies 
listed in the security inspection report have been cleared away. It 
is therefore requested that the monthly report of action taken re­
quired b y cited letter be discontinued.

I a::n lnclos1ng two copies or the report you asked tor, fllld hope 
that they oerve their purpose. 
\'lo Jiave mado a preliminary ez:eminntion ot tm elghtaon collact1ona 
token at nine locatione on my,l!onde.:,• 'l'uesday trip. !lbere was a large 
number of coppor-boar1ng pe.rtiolee on one eolleotion (ll-104L) taken on 
Higm1ay 84, seventeen ·mles north ot E1gl:may 66

and aoa.ttered occas• 
i 
onal particles throJJ.ghout the series. The collection teken at tho 
Blt"lle location imcodiately' following R-l04L eho'\YD practically no copper. 
A 1orge l)art of the n -104L is of a granular mnterial untamiliar to us, and 
, the copper indioat1ona ori,:.inate principal ly 1n l'lhat are e.pparontl'1 
aggregations of finely (ona .. meron) granular material of overall sizes 
in tho neighborhood of thirty microns. Some cop_per _part! ,lea, hor.-
ever, appear to be solid nnd o,Paque. The passage of t-, automobiles while 
this oollection uas being made is a complicating fe.ctor. It is hard 
to aee how they mieht he.Ta been a eourco ot coppor, ho,raver, unlean it 
nao a question of stirring up aoI!lo :trom dust on the -pavement. 
We intend to do some :1"urther chemi.eal work Tii th theee colloctions, 
but I doubt if muoh nen relevant information 11111 be obtained. 
Hy tentative conclusion is that no ~idcspread significant dispersion 
or copper- bea't'ine; particles ,vas present in tbe atmoaphere in the rc"ion 
covere.:1 at the timo the eollcct1ons wore made. l,o det1nita statel':lcnt 
is possible about the one heavy copper collention: it should be prosumod 
to be of local origin until come evidonee to the contrary ic 'found. 
~e route at tho collocting trip included Paatura, Santa noaa., junc­
tion of Routes 66 and 84, ond Las ·Ve.:;aa on J!ondey af'ternoon. On Tuosdey 
morning it included. Las Ve3as, Canonr,1to, Glorieto. end ecos.

1949. Impaotment equipment, develop9d 
in conneation 1a th the sarosol research proJect ot the New Mex1 co School of !lines, 
was available, and it was decided to make systematic collections ot airborne me.ter­
-iel. in the hope ot obta1nill8 material that could be associated .-1th the t1reball. 
For the present report it is suftio1ent to state that the equipnant processed air 
at the rate ot about J4 11tera per minute, the particles being separated f'rom the 
air by -impactment against en adhesi'f9-coate~ plate in an air jet. Appro:d!natel.y 
ninety per cent of airborne particlee with dianeters greater than one micron are 
collected. 
Tho 
adheeive used. on the collecting plates (mcroscope slides) waa a glycerin­
gelatin tlixture w1th an a.dd1tion or rubeanic aeid (dithiooxamide. ) 'l'lus reagent 
was used to enable identifioation of copper or copper compounds; it also enables 
identification of nickel and cobalt. After ?C:lking the eollaotions, the slides were 
covered with e. Saran til::l, after which thoy were exposed to strong aomonia vapor 
for r1:tteon Jninutes to effect partial ao lution or any copp_er or copper oxide parti­
el.Gs. 
R ESULT S 
'?he first oolleotion was made at 10:00 a . m., .ruly 25, about thirteen and one-
he.lf houra after the fireball was seen. The air wan te.lcen about twelve teet above 
ground lovel, on t he Ol!!'.IJ>UO ar the School ot Uines. Tho first run was i'or three min-, 
utes, ll['COosaing cbout 102 liters of air. Sevoro.l large particles wero :round in it 
that gave J)ositiva co pe.r teats. In at least ono or these the copper reaction was 
aeen petore the cn::mx>ni c tro~ont, indicating the presence 9f at least a trace of a 
aoluble copper co~pound. The sizes of particles aoon in tho first oollections ranged 
up to over one hundred microns in the largest dimension: the largest particles gave 
tho impression o~ bein.g f'r8gl:lents or a so:i:ievm.at f'ibrous material, llith the smaller

become cp;ite esoarce. At the same tine, the counto have beccte quite large in tile 
:.s:ncllest aizo group. 
SIONIFICA~CE OF RESULTS 
If 1 t were possible to SflY that particles giving a copper test are generally 
very rare in eollectione near groimd leTel in this locaJ.lty, the above facts t'.Ould 
bo highly s!gni1'1cant. It l1appens, however, that collections have been :-:,ode at 
Socorro over only-a short period, and not .muoh e.tten1i1on has been given to !denti­
fica.tion ot copper coJ:lJ)ounds. ::aowever, after the copper indieetions had been round 
in the present sories of: collectio•,s, some collections were round on file that hod 
been made on plain glycertn-3aui.tin on july .1,, 1949. -These r.are oovered ,nth the 
Sarun fi-lm and rubeanic eoid C!Jld an::.on1a were appliod by d1 tfusion through tho ·ttlm. 
A few copper indications were found, al!nost all the i:e.rtioles being in the 30 micron 
size group. Some other co11ection.s were made early 1n ~uly tbo.t will be e::lt8!ninod 
tor· 'lopper when they are treed !"roe other tests. lil add1 t1on, oce~ional colloot1ons 
will be examined. tor copper in the futll!'e,   and 1t may be possible eventually to add 
so:neth1ng to tho information now presented. 
COllCLUSION6 REGARDING COPPER 
In view Qt the above fa.eta , it i,eem:, very hazardous to draw any: definite con­
clusion associating ~he coppe~-bearioo perticlos collected with the fireball or 1uly 
24. Th.are a till is, hwoTer,   a residuum or poasitdlity ot such associations men 1 t 
is conoidored th c.t partic!.ss ot 1hc smallest s1 ze group did not appear in largo 
numbera until some 35 hours at'ter the po.esege of tl;le fireball.

Attention is called particularly to the l arao !lumber ot small particles in one 
at the 145-l/2-ho-.ir collootione. The actual nl.I!lber in the colle'ltion was 140, tor 
the r ive-oinute run. l.!ost of these l'lere in the size range of' tTJO to f1ve microns• 
and the principal difficulty in assoctattnc them 111 th the fireball is that a five­
micron par\1cle cannot tall J!lUOh more tho.n l0,000 foot in 145. 5 hom-s. These part1-
olea could have ccr:ie down from a greater height only it' sol:!& downward motion hfld 
tc.k:en place in port of the a1r 1nvolvet. 
It s hould be oantioned. that collections were t aken during tbe at'ternoon of Ju13' 
27, at several pointa eouth end east ot Socorro, tbs fartb.eot being near Binche:a. 
These oolleotions ocntainod pcrtiole~ giving copper indications, the :particles being 
i n tho •a;?¥!) range ot sizes as those collected in Socorro at about the &a.":le ti'C'.b. 
It is perhaps noteworthy that the cop_per- boari ng particles 1n all these collec­
tlona were of opaque material. I.oat ot the co:;,per minerals tbat h uve previously-
come to our attention 1n collection• rrom the air have been oolored material, blue, 
green, red, or yellow. 
C OBALT AND NICKEL TESTS 
In the 2 t00 J.l• coll~ction of J"ul.y 26, three quite re:::iarkable particles were 
found that save very strong coba1t indications. The particles were apparently por­
:reot spheres (at l east thoy were pori'eetly circul.ar in cross section), twelve mic­
ro!ls in diameter. The reaction with rubeanie e.eid, after at!nOnia trentmant  ,  pi•o­
dueed a dense yellow-ten halo, eixty microns 1n diameter. The color v.ao not quite 
so clear es with pure cobalt: the e.ppearance sU;;gestin.g e. high-cobalt com,vosition 
with so~ metal. prosont. Such particles are quite uniqne i n the axporionce or the 
present.  , It' these particles wore of meteoritic orictn they cwld, in tho absence 
of verticul oir IJOV«llSnt, have f'al:len a d1stO!loo of the oi·der ot 20, 000 feet 1n an 
i nterval or 41. 5 houra. 
Two particlse giT1ns nickel indication.swore round. ~a is quite nomvl, llo ,­
ever. It anything, the number is smaller than x::ight have been expected in material 
of aurt'aoe ori<;in. The collections ware not given acid treatnent: additional nickel 
indieations might h &Te been 'i'ound it t his had been done. 
A oUOGEB TION 
hile the r&aul.ta o!' the present investiga:Uou ahould be recarded as negatt-vo 
or,inoonolusive
