During the evenings he gave them practical demonstrations of the application of tourniquetsa，bandages and the like，while Uncle John and Ajo by turns posed as wounded soldiers.Gys was extraordinarily deft in all his manipulations and although Maud Stanton was a graduate nurse—with little experience，however—and Beth De Graf had studied the artfor a year or more，it was Patsy Doyle who showed the mostdexterityb in assisting the doctor on these occasions.
"I don't know whether I'll faint at the sight of real blood，"she said，"but I shall know pretty well what to do if I can keep my nerve."The application of anaestheticsc was another thing fully explained by Gys，but this could not be demonstrated.Patsy，however，was taught the use of the hypodermic needle，which Maud and Beth quite understood.
"We've a big stock of morphia，in its various forms，"said the doctor，"and I expect it to prove of tremendous value in comforting our patients.""I'm not sure I approve the use of that drug，"remarkedUncle John.
"But think of the suffering we can allay by its use，"exclaimed Maud."If ever morphia is justifiable，it is in war，where it can save many a life by conquering unendurable pain.I believe the discovery of morphine was the greatest blessing that humanity has ever enjoyed.Don't you，Doctor Gys？"The one good eye of Gys had a queer way of twinkling when he was amused.It twinkled as the girl asked this question."Morphine，"he replied，"has destroyed more people thanit has saved.You play with fire when you feed it to anyone，under any circumstances.Nevertheless，I believe in its value on an expedition of this sort，and that is why I loaded up on the stuff.Let me advise you never to tell a patient that we are administering morphine.The result is all that he is concerned with and it is better he should not know what has relieved him."On a sunny day when the sea was calm they slung a scaffold over the bow and painted a big red cross on either side of the white ship.Everyone aboard wore the Red Cross emblema on an arm band，even the sailors being so decorated.Uncle John was very proud of the insignia and loved to watch his girls moving around the deck in their sober uniforms andwhite caps.
Jones endured the voyage splendidly and by this time had convinced himself that he was not again to be subject to the mal—de—mer of his first ocean trip.As they drew near to their destination an atmosphere of subdued excitement pervaded the Arabella，for even the sailors had caught the infection of the girls'eagerness and were anxious to get into action at the earliest moment.
It was now that Uncle John began to busy himself with his especial prize，a huge motor ambulance he had purchased in New York and which had been fully equipped for the requirements of war.Indeed，an enterprising manufacturer had prepared it with the expectation that some of the belligerenta governments would purchase it，and Mr.Merrick considered himself fortunate in securing it.It would accommodate six seriously wounded，on swinging beds，and twelve others，slightly wounded，who might be able to sit upon cushioned seats.The motor was very powerful and the driver was protected from stray bullets by an armored hood.
In addition to this splendid machine，Mr.Merrick hadsecured a smaller ambulance that had not the advantage of the swinging beds but could be rushed more swiftly to any desired location.Both ambulances were decorated on all sides with the emblem of the Red Cross and would be invaluable in bringing the wounded to the Arabella.The ship carried a couple of smallmotor launches for connecting the shore with her anchorage.
They had purposely brought no chauffeurs with them，as Uncle John believed foreign drivers，who were thoroughly acquainted with the country，would prove more useful than the American variety，and from experience he knew that a French chauffeura is the king of his profession.
During the last days of the voyage Mr.Merrick busied himself in carefully inspecting every detail of his precious vehicles and explaining their operation to everyone on board.Even the girls would be able to run an ambulance onoccasion，and the boy developed quite a mechanical talent inmastering the machines.
"I feel，"said young Jones，"that I have had a rather insignificant part in preparing this expedition，for all I have furnished—aside from the boat itself—consists of two lots of luxuries that may or may not be needed.""And what may they be？"asked Dr.Gys，who was standing in the group beside him.
"Thermos flasks and cigarettes.""Cigarettes！"exclaimed Beth，in horror.The doctor nodded approvingly.
"Capital！"said he."Next to our anodynes and anaesthetics，nothing will prove so comforting to the wounded as cigarettes.They are supplied by nurses in all the hospitals in Europe.How many did you bring？""Ten cases of about twenty—five thousand each.""A quarter of a million cigarettes！"gasped Beth.
"Too few，"asserted the doctor in a tone of raillery，"but we'll make them go as far as possible.And the thermosa cases are also valuable.Cool water to parched lips means a glimpse of heaven.Hot coffee will save many from exhaustion.You've done well，my boy."
