 The Tarzan and the Diamonds of Arshere. Tom joins the Tarzan Gregory Safari and agrees to proceed with them to their common goal to in Baca and the forbidden city of Arshere under the leadership of the Eight-Man. Tarzan and his friends are searching for Helen Gregory's brother, Brian, while Tom is after the legendary gem of the Hesseharians, the father of diamonds. Helen vanishes mysteriously, and Tarzan, leading the expedition to proceed under Tom and Darno, goes in search of her. On the trail, Larsen stumbles into what appears to be a man-built causeway, and Darno finds, scratched on the wall, words printed in English. Luke, a word in English. Nella, but this cannot be English. I have never heard that word before. A moment, Darno. Let me look at it. Ah, look at this. Examine it closely. What? I can make no thing of it. It looks like... Tonya depressed, like a word written upside down. Exactly. You see how the letter E is reversed and the L inverted? It is the word Helen. No, then no, you are right. Then she must have been here in this causeway. Obviously, my friend. See here, following the word Helen another word. Captive, also inverted, and a mark which may assume to be an arrow pointing in that direction. But why are the two words written upside down? Yes, I cannot understand. Place your back to the wall and scratch the word Helen with your fingernail. You will write upside down. Oh, of course. Then, my little Helen is a prisoner, but of whom we knew that. Yes, Wolf, if we knew that. Well, what we've been going to do now, follow this tunnel in here, or go to the jungle? I would say follow the causeway. It is wide enough to take the entire safari. It will save us cutting our way through the jungle. Yo, and with the torches, we can see first. Oh, that's a good idea. Bien. Then we shall go up and start the natives into the causeway. Come, Wolf. We will all go up, Darno. I anticipate trouble with the Mburi and the Minas. Trumbo? É pour quoi? Yeah, é pour, é du tout. Those fellows have been all right out in the open. But down here, they don't know. We will soon find that out. Come down, Wolf. Be careful of these steps, my guy. Hey, Wolf, here. Hey, Mburi, come. Wanda, Larsen, come back. Shut down the no-catch'um. Yeah, some bully. There ain't no shatani down there. No tambi, doctor. Look, we go this way, Mburi. No more cut trail. Go plenty fast. Where won't Darno go? We go to Big Hole along Big Road down there. No. No can do. Watamishi gong a tapika in Devil Hole. Get sick. That place better Watamishi. Plenty taboo. There is no shatani. Not catch'um, we devil. Not there, Mburi. We go to come along us. No can do. Plenty taboo along that place. Watamishi no go. Mburi no go. But we pay dog, we pay some bully. You go now, eh? No go. This place taboo. That place taboo. Mburi, now Watamishi no go, no more. All come to here plenty taboo. But if we stay topside and cut trail, you go there. No more go. No can do. All this place taboo for Black Boy. You see, Darno, it is useless. No argument will persuade them. Whether we follow the causeway or continue to cut trail, we must go on without our bearers. Well, those Black Rascals would rather tie on the spot and break one of their hidden taboos. If I had been allowed to use the fifth committee... There will be no whipping wolf. If they will not go, they will not go, and flogging them will not help matters. On the contrary, they would very likely turn on us. Yeah, sure, that's right. Well, then we camp right here, eh? And wait for Tarzan to come back if he does. No, no, we will go on. Ma Petitelein has been taken through that causeway. We must follow. We may even find her in there. We must be somewhere near to Invaka, perhaps even to Acheer. We know Ellen is alive. We can go on much more quickly with the native. Alors, what do you say, Larsson? Well, he was hired for the trip. In and out, we ain't injured. Boom, boom. At you, we're... Uh, Mokra said it. He can make better time without the native. Very well, and you and Larsson have the supplies brought here. We will go over them and make up individual packs of absolute necessities. Throughout the remainder of the day, little tome, Wolf and Larsson sort over bales, bundles and boxes, sitting here, rejecting there. Only such bare necessities, as are absolutely essential to their journey, are selected and stacked near the opening to the causeway. Well, now we bear lieutenant our supplies for the rest of the trip. Ah, they won't take us far. They will take us as far as necessary. I don't like the tone of voice you say that even. Just what do you mean? When these things have given up, we will no longer need supplies of any kind. Exactly, Mokra. Either we shall be in Acheer or dead. But according to the map, we are very near to Mbakka. Yes, darn-o, to Mbakka is a mountain. It is not Acheer. Well, Larsson, you and Wolf make individual packs of this. Let Mbakra's pack be light, Larsson. You may add the extra weight to mine. Yeah, sure. Well, we better get busy, Wolf. Mbully, Hala, 26. Here, up on that. You are positive. You no more go along this safari, Mbully. Mbully, now what the mission? No can do. This place plenty taboo. Bien, bien. You see all this cekula? You take. You go back Longbunga. You give this chit paper to big Franz Waibwana. He give Mbully Pesa. Can do, Buanna. You no come along, what the mission? No, we go on. This chit paper tell French Commissioner where we go. We are ready, Lieutenant. Come, darn-o. Nandezako, Mbully. Mbully, Nandezako, Buanna. That place had big taboo. Much taboo. Here, Mbakka, here. Give me your hand on these steps. Oh, well, we are all ready to go on. We will each carry a torch and proceed as far as possible before making camp. Let's carry out this vain and spooky place. Maybe those natives ain't been so dumb. You know Africa better than that, Larson. If we listen to every native superstition, we would never leave the coast. By the way, have you noticed the rock tone? A mass of tangled roots, vines and creepers? Those things must have been growing there for centuries. Yeah, yeah. Well, this ditch is pretty deep. All of the 20 feet, I would say. I wonder where the other end comes out to. Back there. This was undoubtedly a canal at one time. Where the water it carried came from, I have no idea. It probably emptied into that river we crossed eight or ten days ago. Just look at those huge granite blocks in these walls. Where could they have come from? Nom-tam-nom-tam-nom. A magura that is not a wall. There is none on the other side. This must have been a waft where some large ships were docked. Look up there, that heavy iron ring. Donovetta, you're right. But that ring is stone. Not iron. Look how those blocks fit together. No cement. No nothing to hold them together. And see up there? That's a water mark. Here is the end of the wall. We step carved into the stone like those we saw coming back there. Hey, the canal makes it turn half. Maybe we get the camp half. No, we go on, unless magura is there. No, no, let us on team. Look out half. Some rocks and dirt have caved in. Baby, look at that on that big rock. Some kind of a hidden shrine. Bring those things closer. Look here, Donov. These carvings and hieroglyphs. Nom-tam-nom-tam-nom. They are ugly enough. They look like death heads. Skulls. Carved into stone. I do not like them. They are gruesome. Come away. I don't like them either. Look how those empty eyes are getting stared at us. They make me feel like someone was watching us. Perhaps someone is watching us, Wolf. I have had the feeling for some time. That's a grand eye, too. But I did not wish to mention it because of... Because of me, Lieutenant. Ho-ho. You are all acting like little boys. Frightened by what their imagination places in dark corners. Brave little magra. Nevertheless, remain close to the lieutenant. I know her myself. I do not wish to see you vanishing thin air. The tunnel straightens out again. I can't find any dust. Just light way up there in front. Hurry up, eh. I think we've been come to the end of this thing practice soon. You see light? We thought we'd have his own. But it cannot be daylight. It was just beginning to get dust when we entered the causeway. It is probably moonlight. I think Larsen is right. We have reached the end of the causeway or some sort of opening. I won't be sorry to get out of this hole. There's curls. Watch every move you make. Hold yourself together, Wolf. Those things are merely age-old carvings placed there by a long forgotten ray. Aye, aye, aye. I know. But whatever they are, I don't like them. They look to me like a morning. I feel like they were swallowing us. All hieroglyphs look practically the same to me, Tom, but those with the carvings of those horrible faces, do you suppose they bear any relation whatsoever to the ones we first found? Aye, aye. I cannot say, Donald. I made a copy of the first ones we found. But you did not copy these others. No. No, to tell you the truth, these faces were not agreeable to me either. I was as anxious to leave them behind as our friend Wolf was. Well, yeah. At the Naval Academy, I made a study of some of the more ancient languages, Egyptian and some others, a set idea they spoke and talked. I did not get so far with the arrow glyphs. Wish now that I had devoted more time to that study. It is an interesting subject. What let us go on, Larson, is quite some distance ahead. He has perhaps found the opening. Larson! Yes, sir, Lieutenant! Have you reached the end of the causeway? Hey, Ben, picked it up.
