Dear Walton 
I m very happy to have year letter of July 30th and your 
relianoo upon har4 token laeasureEieats* partioularly as w» were un- 
able to buy or borrow a photographic rig* Par superior to the oiae 
about which I sent you a oircular is tlj® so-called Eecordak, sold 
by a subsidiary of Eastiaaa# It is really of tli® most amrvelous 
thi33^s that I have ever seen and one tlmt I «n sure would turn out 
a satisfactory job on the Idtlsodlds, W© iiad planned to run a series 
of tdiotographio oeasurOTents against the hand taken ones, la order 
to determine the relative accuracy of tte former, I tried imrd to 
borrow a Eecordak set-up, but the Mg boas of that oorporation Is 
on vacation in Lkiixie and can’t be conveniently reached for a decision, 
I would that I could lave given the ttiing a try-out on tlxis trip* 
Our sailing ^te from Seattle has been postponed a week, 
end so I shall delay a bit before leaving Washington, A| the 
present rate, I can be in Monterey or San Fraaolsoo on the ISth 
if I case by train, or on the IBth if I eme by air* la aiy case, 
1 shall xsire you as tory actual arrival in Monterey so that you 
nay leave a TOssage at idie alrpO:rt tolling a© of your whereabouts* 
Tim plane stops in Del Mont® for about ten minutes, which would 
give me enough tiiae to reiwl tt letter from you, I would be glad 
to pay you postage, espeoially as you may need to make it speoial 
delivery after getting ay wire. For tte train trip you could write 
me a letter in oar® of the station master in Los ingeles, where the 
train stops for about l§ minutes* You will be reoeivlng a wire from 
me tward the end of this week or ^rly next* 
Do not let me upset imy plans that you may have made, I 
aa authorised to travel about in California, so I can almost look 
you up any place that you m&j bo. If you have vaoation plans be- 
fore school opens, don’t let me interfere with them, 
Simerely,
