Subs are great craft, very compacp, no space to waste. Men aboard 
get quite used to it; some bunks are just 18" below those above. One gets 
quite clever at stepping through (like hurdle racer almost) little 4-foot 
high, 2-foot wide doors; some are couple of steps up or down, as deck levels 
are not same in all compartments. 
The toilet is quite a mechanical contrivance. All inlets from sea, 
like flush water, have two valves, air alst has two, also discharge opening. 
Seems very complicated at first, but very logical and simple after you get 
hang of it. After using, one opens two flush valves, one after other, before 
water flows. Then you pull lever to dump bowl into hopper below. Then open 
air valve, and pull change lever right way, watching pressure gauge up to 
20-25 lbs. Next open outside discharge valve with (life up and down lever), 
open gate valve by rotating wheel, and last move charge lever the other way 
to discharge side; when container below closet bowl is blown clear. Last, shut 
off valves. 
Had nice lunch aboard in small ward room. It is just separated 
from rest of compartment by a light xxjdsxtxtiEHx partition which, because of 
type of sub and need for getting out batteries, does not extend to deck 
underfoot and has no doors into staterooms just off side of wardroom or 
portion of crew's quarters just forward of it in same compartment. Just two 
toilets on whole sub. 
After lunch went ashore to see what possibilities of hiking inland 
were and after great deal of hacking at thorn bushes which formed an almost 
inpenetrable wall just back of beach reached a little more open ground with 
so many lava dykes that it was rough going. Result was that without compass 
we made a sort of S sorties twice paralleled beach and so made very little 
headway inland. Constant hacking and blazing of trail, breaking over small 
trees; and slicing off ends of cactus pads, this made one of best blazes.
