Washington City, May 19.- A dispatch was received at the navy department yesterday announcing the departure of the cruiser Charleston from Acapulco on Sunday night. The dispatch also stated that the insurgent vessel Esmeralda was 8till there. No information can be obtained as to where the Charleston will go next, but it is thought that she will go down the coast of Chili. A telegram from the City of Mexico says that nothing bas been seen of the Itata, and that she is probably now off the coast of Central America, having been supplied witu fuel by the Esmeralda. Mot Afraid of a Flght. In an interview at Acapulco Sunday an officer of the Esmeralda said: "We will try to get coal here, but if this is impossible, we are sure of getting it within a few hours sail. We are not afraid of a conflict with the Charleston, but our orders are to be prudent and not provoke a conflict." He dia not know whuther the Esmeralda would now go to Chili, but said the captain had received a long cipher on Saturday which probably directed her future movemeuts. The Importauce of the Capture. It may not be known to the general reader, but the fact is that the capture of i the Itata is a matter of great importance to Uncle Sam. If she lands hér munitions of warsafely the Chillan authorities will have a good claim for large damages against the Uuited States; for the principie is the same as tbat upon which the Alabama case was decided.when England had to pay a"pretty penny" for letting the Confedérate privateer get away. The Itata not go Slow. A telegram from San Francisco says: "Peruvian Consul Holloway in talking of the probable escape of the Itata says: 'Many singular misstatements have been made in regard to the Chilian steamer. In the flrst place the Itata is a twelve-knot vessel, and she should reach Iquique, a run of less than 5,000 miles, inside of eigbteen days. Wheu she left San Diego, about May 6, she had 800 tons of coal aboard, and sne does not buru over fifteen tons daily. Such being the case, she has enough f uei to last her about fifty-four f] AVH.' TesUmooy of Deaerters. "Three deserters from the Itata have given tbeir evidenee to this effect. She had on board ninety sailors and sixty marines when she was ia port at Saa Diego, all instructed to secrecy. She carried four sixty-pound guns hidden under canvas with hersmaü arms in the forward hol'l. The soldiers were stowed away there also, their food being sent to them froin the deck. Every appearance of the vesse) beiug prepured for war was removed two days before she steamed into San Diego, when she looked like a nrst-class mercnantman. The Frograiume Laid Out. "The programme was for the Itata to get arms fröm the Robert and Minnie, and when in the tropics to transfer them to the Esmeralda, which wquld escort her to Iquique. If the trip was made without interference, so much the better, but if not the Esmeralda proposed to do battle. The Esmeralda and Itata were commanded from Iquique to St. Lucas by each other's masters, who exchanged to their rightful commands at the latter point. Some informatioa has been obtained which leads to the belief that on May 12 a transfer of arms and munitions of war was made from the Itata to the Esmeralda at Fichilinque, on the cast of Bouthern California." The British Lion Growls. "A copy of the Chilian Times bas reached here by the steamer San Bias. It says the British forced an apology from ;he insurgent man-of-war Blanco Encalado just before the latter was sunk by the torpedo boats. The Blanco was en?aged in blockading Iquique when she, with other vessels of the blockading fleet, ran out of coal. Two Englisti and German merchantmen were lying side by side, both coal laden. The rebel fleet took hold of them, on the pretensa that they svere in range in the event of firing, aud towed them out to sea, despite the protests of the captains. Had to Apologize or Fight. "Out of range of the fort's guns, the insurgents made a forced purchase of such coal as they needed. They voluntarily paid au extravagant price for it, but nevertheless the captains of the vessels reported the matter to the British Admiral Hotham, who gave the Blanco the option of apologizing or fighting withiu twenty-four hours. It was then 11:80 a. m. Precisely at noon the Blanco ran up the British and Germán flags above the rebel standard and fired a royal salute."
