Colonel Sibert, the Genius of
 Gatun, Contributes ln- teresting Paper to the Na- honal 0eographic Society

nAofilN1lONs ftD. Zb.-lsleut. Col. wilnam M. Sibert, U. $. A., the builder of the Gatun locks, the Gatun Lam, the breakwater at Coion liar. bor and the excavation of the channel between the Gatun locks and the At lantic Ocean, has written an interest iIg article on the Panama Canal, his | first contribution on tne subject. for the National Geographic Society al ! Washington. D. C. In his article. Col
 Sibert asks this signincant question:
 Now that the canal is essentially Finished, what are the American peo- pie going to do with 1t? Shall the new markets brought into existence on the Pacific shores of Central and
 south America by this new cheap transportation route be supplied by
 the United States or by foreign countries? In my judgment, that de- bends. more than anything else, upon whether the Congress of the United States enacts such laws as will bring into evidence United States mer- chant marine engaged in foreign com merce."
 If there are any people who yet hold the idea that the water of the Atlantic and Pacific will mingle in
 tie canal Col. Sfbert dispels that
 idea with the two statements that for about S2 miles the canal is S5 feet above the level of the oceans and that
 water VII not flow uphill"
 "A little to the north of the Gatun locks the American and French ca nals intersect.' continues Col. Sibert
 Had the French canal been com
 pleted 1t would now be cut of date,
 for its locks would not be of suhi- cient size to pass the fboats that
 would now offer. In 1912 Gatun had probably the greatest influx of mala-
 rial mosquitoes in it's history The
 sanitary department determined t- locate all the breeding places for mos quitoes near Gatun, catch mosquitoes | at such place, and after painting them , turn them loose, and 5etermiLe from
 the color of the mosquitoes caught
 in Gatun from what point they came. - went down there Cne morning 10 see how they were caught and , painted. Mosquito ibars were sus'
 pended from limbs tied up at the bottom They had thousands of mos s ouitoes in them ready to be sprayed , with oo.ored liquid and the sani'
 tary inspector was asked how he eaucht them. He said, We have a
 mcre scientific way. but this had to a be done in a hurry. We simply let the
 mosquito bar down, as you would open a bc5, left one side Of it open 9 and put Jamaica negro in there TOT D hait. As soon as the mosquito par
 was full the bait was removed ana
 the end tied up. l saw a Jamaica
 negro standing there. John. were you
 he tait in that bar l asked, and ne
 replied, Yes. boss; that is the easiest money I ever earned-ten cents an y hour for sitting there and doing noth p ing but just inviting the mosquitoes
