The Conservative * of the Maine. Wo also inspected the fortress prison , Las Cabanas , and went through its long and devious under ground passages leading to the numer ous dark dungeons. Appalling in its magnitude and grandeur , and stupendous deus in the outlay of labor and money , it is a disgrace to civilization a relic of inconceivable barbarity. We went also to Morro Castle. It is interesting more on account of its massiveness and de sign , enormous cost in labor and treas ure , rather than its usefulness as a modern defense. A visit was made to the grand old fortress , El Principe , built without regard to cost , before the days of modern artillery , but after the per fection of the science of permanent fortifications. The cemetery is also well worth a visit. Puerto Principe. About forty hours on a Spanish steam coaster brings one to Nnevitas , the port of Puerto Principe Oity , capital of the province of the same name. The city has between 85,000 and 40,000 popnla- ti6n , and is also clean as a pin , another object lesson for our own cities in that regard. American Inconsistency. Indeed , Americans may not be the only people who practice not what they preach , but they have high ideals and most decidedly like to enforce them upon others. One of the greatest in dustries of our country is the manufac ture of intoxicating liquors. Yet we prohibit the Indians from making and drinking tis-win. At a council of the Apaches the chiefs protested. "White men make whiskey ; white men drink whiskey ; why they no let Indians make tis-win drink tis-win ? " No one could meet the argument , and all the officer could say was : "Well , General Orook has ordered me to have it stopped and I have to obey , not question , his orders. " Then a small faction of our people con ceive that American soldiers should not be allowed to drink beer , and ally them selves with those who want to sell sol diers poisoned whiskey. And run shady dance houses and concert halls , and get congress to prohibit the sale of beer on any military reservation , while a gin mill is running in the basement of the capital and congressmen wipe their mouths while they vote for the prohibi tion. Truly consistency is a rare jewel and probably we have no right to ex pect to find it in our own acts. Political Situation. Everywhere I have been I have tried to sound those I met , in a quiet way , for my own information , as to their own feeling and that of ( he Cuban people on the form of government they want. Without an exception they were in favor of annexation to the United States , and they aver that to be the feel ing of all of the intelligent and educa ted classes of all property owners and business men , and annexation to the United States is opposed only by the ignorant who are still following the ignis faluus "Liberty , " of which they have no true conception and which they have not found under the occupation by American troops , and which they fear they will never find under the folds of our flag and which I am quite sure they will never find at all. I have yet to meet any man who believes that the Cubans can establish and maintain a government that will be any more satis factory to the United States than that of the old Spanish regime. But suppos ing they can , supposing they establish and maintain an ideal government , they will have to have all the costly machin ery of a general government. They will have to create aud maintain a navy and an army , a custom service , light house service , and fortify their harbors and maintain ambassadors and ministers at the capitals of all governments , and , if they have any commerce , consuls at all the great ports of the world and cen ters of trade , and worst of all , Cuba would be confronted by the tariff walls of all nations , while she is now begging for tariff concessions from us. On the other hand , annexation to the United States means for her the most liberal form of government that of one of our sovereign states , and probably more , for in that event she would doubtless retain all her land as did Texas. She would be exempt from all the expenses of a general government enumerated above , but best of all she would have free trade with all the states the best market in the world for her products and for which she is now clamoring for concessions only. She would have the protection of the gen eral government , assurance of a stable republican form of government and se curity for foreign capital investments which she so sorely needs to develop her rich resources. This is only a base outline of the pros andcons in the case. Never in the his tory of the world has a people had such an opportunity. Cuba could well af- for d1 to pledge millions for annexation. Willshe ( avail herself of the opportunity ? That is to be decided by counting noses with all the chances that the majority settles a question right. CHARLES MORTON , Lieutenant-Colonel , U. S. A. SCIENTIFIC MISCELLANY. The electrograph of Prof. Lancetta is now at work in several Italian ob servatories. It consists of an elevated wire or antenna , connected to earth through a coherer , which is affected by electric disturbances in the air and acts upon a recording apparatus. A light ning flash , for example , causes the co herer to ring n bell and make a pencil mark upon a revolving clock dial. With an antenna forty feet high on an eleva tion without surrounding obstacles ! a thunder-storm can bo detected more than sixty miles away , and the appara tus is expected to do valuable service in signaling the hail-storms so much dread ed by Italian vine-growers. For producing low temperatures down to GO ° O. below zero , M. d'Arsoiival recommends chloride of methyl evapo rated in a porous vase. To reach 112 ° or 115 ° below zero , liquid carbonic acid or acetylene may be used , and may be conveniently dissolved in acetone. Liquid air offers the best means of ob taining greater cold. This should be slowly dropped from a silvered glass flask through a rubber tube into a quart vessel of silvered glass with double walls , the vessel being placed in a bath of gasoline. A little more than an ounce of liquid air suffices for giving 194 ° below zero for an hour. A remarkable dependence of certain plants upon others of different kind seems to have been discovered by M. Noel Bernard , a French botanist. The orchids produce many seeds , some of them millions to the single plant , yet they are very rare plants , and it was long supposed to be impossible to grow them in any way except by transplant ing the bulbs. Success with the seeds was at last reached by sowing them in soil that had contained the adult plant. From his investigation , M. Bernard concludes that the seeds germinate only after they have been penetrated b a certain species of fungus , and that in fection of the soil , which would result from the roots of the older plants , is necessary for the cultivation of the young plants. Mysterious dark bodies ; have been seu occasionally to cross the sun's disc. 'An English astronomer has collected ac curate dates of nine of these transits , the earliest being June 6 , 1761 , and he finds that these dates indicate the ex istence of two unknown planets , within the earth's orbit , with periods of alaout 174 and 20 days respectively. One of these bodies must be hearer the sun than Mercury , with a mean distance of about 13,000,000 miles. The other is calculated to revolve between Mercury and Venus , at a distance of about 61- 000,000 miles , aud should have a diam eter of 1,700 to 2,000 miles. At its most favorable position for observation , it would appear as a third magnitude star 80 ° from the sun. Sunflower pith proves to have a spe- ciflo gravity of only 0.028 , while that of elder pith hitherto thought the lightest solid is 0.09 , and that of cork is 0.24.
