 TO CORRESPONDENTS depart
 ment of Answers to Correspondents is always ready to answer questions of gen. | eral public interest, but it cannot under | take to guarantee an answer at particu- 1 lar time. Last week one correspondent
 writing from the interior asked that the
 answer be printed on Friday. The letter
 of inquiry did not reach this department | until Friday afternoon. Another asked
 in a second letter sent three days after l the first why the question was not an | swered. The question asked was one in- | volving questions of international law | that required several hours research in 1 law books, and as the department has | not devote hour after hour on any one l day to securing an answer but must de-
 vote such time to the inquiries of all, | and secure as many answers as l possible. Questions the answer to | which require a long research to obtain | are looked up at such leisure as can be | devoted to them, but none are unneces- | sarily delayed. Answers are printed as | soon after being set in type as possible,
 and if correspondents do not see the an- | swer in print as soon as they expect they 1 should not feel diSapDOinted.
 1 MILITARY SERVICE-M K, City. In
 case of war any nation has the right to
 call upon it's citizens. If such citizens | have taken up their residence in the | United States and have not become citi-
 zens thereof they would be in honor
 bound to answer such call but if they | did not feel inclined to do so this depart
 ment has not been able to discover any l law that would authorize the country is l suing the call to come to the United States and compel them to serve. There 1 are some foreign countries which claim l the military service of all their citizens, | and if they, after expatriating themselves l without having performed that military | service, should return to the country of l their birth, would be required to perform | that duty. For instance, Germany holds | that every one of its citizens must per | form military service. If such an indi- NNLuodl, HdE4HS iS4t HIS country "ltI'1t | having performed that service return to l the land of his birth, though he may have | become a citizen by naturalization he will | have to do military duty for a period not | longer than he would have had to per
 form such originally, unless at the time | he left his country he was given cerd- | fcate of exemption. By courtesy the l German Government allows a naturalized 1 citizen of the United States who owes
 military duty to visit Germany for q pe- | riod of four months, but if he remains | beyond that time he is liable to be seized | and forced to perform that duty The l United states cannot protect natural l ized citizen compelled in the land or ms l birth to perform a duty which ne neg | lected to perform before he became | citizen of the United States.
