They learned that the particular insect, the germs of which are sent to Bona, is a variety of remarkable habit. Although living in distinct colonies, they are symbiotic, and do not grow to perfection unless there is a certain beast living near them. Such an instance is by no means isolated, for there are, on Earth, many forms of bacilli, for example, which, to arrive at perfect development, must be placed side by side with amœbæ; if they are thus placed on culture-plates and both fed, the samples taken from them for independent culture must also be symbiotic, and contain both bacteria and amœbæ so that both may grow together, if results are to be depended upon. For this purpose the people at Kulametik imported an animal of enormous bulk from a distant land called Carakulak, in which district alone it was bred. On Jupiter there is only one language, which is spoken in all parts of the planet, and telepathy is in universal use, consequently, when the Bonians sent their message, all the people on Jupiter on the same ‘waves’ disturbed by the Bonians received the same message. It so happened that the people at Carakulak received the message, which was the cause of their excitement when the _Regina_ settled in their midst, for they had been expecting and hoping to see the ship which had travelled so far in so short a time. Understanding what was wanted, and knowing they sent the large animal to Kulametik for the same purpose, they no doubt considered they were doing the Terrestrians a kindness in presenting them with one of the beasts that were necessary to the full development of the insects at the farm at Kulametik, where the naturalists in charge would not have one to spare. These great beasts were perfectly harmless, living or dead, provided death came naturally, or in any other way than from a broken spine; for when the spine was fractured, especially near the throat, there came from the spinal cord or marrow, if exposed, an oozing which was exceedingly volatile, and instantly became converted into a gas so deadly as to cause immediate death to every living thing within a radius of fifty feet of the carcass. When the natives saw the beast slip through the rope and hang head downwards they feared it might slip away altogether and break its weak and brittle neck; this explained why they had run helter-skelter at the first sign of danger.
