ine solution, the
tissue dissolved into thin, pink suspension.

In the laboratory they found two or three of the guinea pigs in the last
stages of the infection, and injected them with a tiny bit of the pink
solution. The effect was almost unbelievable. Within twenty minutes all
of the injected animals began to perk up, their eyes brighter, nibbling
at the food in their cages, while the ones that had not been injected
got sicker and sicker.

"Well, there's our answer," Jack said eagerly. "If we can get some of
this stuff injected into our friends down below, we may be able to
protect the healthy ones from getting the plague, and cure the sick ones
as well. If we still have enough time, that is."

They had landing permission from the Bruckian spokesman within minutes,
and an hour later the _Lancet_ made an orderly landing on a
newly-repaved landing field near one of the central cities on the
seventh planet of 31 Brucker.

Tiger and Jack had obviously not exaggerated the strange appearance of
the towns and cities on this plague-ridden planet, and Dal was appalled
at the ravages of the disease that they had come to fight. Only one out
of ten of the Bruckians was still uninfected, and another three out of
the ten were clearly in the late stages of the disease, walking about
blankly and blindly, stumbling into things in their paths, falling to
the ground and lying mute and helpless until death came to release them.
Under the glaring red sun, weary parties of stretcher bearers went about
the silent streets, moving their grim cargo out to the mass graves at
the edge of the city.

The original spokesman who had come up to the _Lancet_ was dead, but
another had taken his place as negotiator with the doctors--an older,
thinner Bruckian who looked as if he carried the total burden of his
people on his shoulders. He greeted them eagerly at the landing field.
"You have found a solution!" he cried. "You have found a way to turn the
tide--but hurry! Every moment now is precious."

During the landing procedures, Dal had worked to prepare enough of the
precious antibody suspension, with Fuzzy's co-operation, to handle a
large number of inoculations. By the time the ship touched down he had a
dozen flasks and several hundred syringes ready. Hundreds of the
unafflicted people were crowding around the ship, staring in open wonder
as Dal, Jack and Tiger came down the ladder and went into close
conference with the spokesman.
