Translation of the letter of which a copy is attachedbyBernard McTigue, Chair, Dept.ofSpecial Collections, George A. Smathers Libraries, University of Florida, March24,1993.29Kilometer Oct. 5th, 1887 [In another hand]Animpossible scheme Description of a Transport System for Removal of Rubble Dredgedupby180 Horses WorkingwithFloating Pipes The apparatus that I have in mind should serve three purposes: 1. To separateoutasmuchas possible the rubble beforeitenters into the passage of the excavation.2.To assureanabsolutely complete mixture of rubble before it enters the pipes. 3.Andfinally to have neither a stop in the flow of materialnoranyobstructions created in the pipes causedbystonesorother objects which have avoided beinggrounduppassingthroughthe grills. Inorderto achieve this I propose the following:1.Wearmthe bucketsofthe dredgedwithclaws sothatthey sliceupthe debris before digging it up. 2. When dredgingwecouple a barge carrying 2 ferries ofgroundupdebris of large size where the debris willbediversified alternatelyinsuch a way thatasone ferry fillsupanother emptiesandthe debris is constantly submitted toanenergetic grinding movement .3. After leaving the grinder the debris is sent into a chamber simultaneouslywithapipeofrefilling with a powerfulpump.At the otherendof this receptacle is apipeneck from which comes theendsof the tubes designed to remove the debris to the discharge point. The water pipedinbythe high pressurepumpformsinthe reservoir a relativegapandcarries the debris through the conduits at great speed. All the movementsofopeningcorridors of thegrindingbargesareautomatically regulatedandshielded from one another. .Inorderto realise [illegible]andimmediately the trialofthis systemoneshouldputtogether the following equipment:Ona barge (woodoriron) of about200... we mount two grinders of 40 to 50 ... representing about1/2hour to one hour of dredging work. One should replace the moveable gang-way for dredging withanother thathas2 directions for each of the mixers, one opening being able to closeoropenalternately to each of the sides of thedualgang-way thereby providing access to the mixer. The mixers canbesimplymadeof 2 cylindrical reservoirs with inclined bottoms connectedatthe bottombya chamber with a [illegible] that alternately opensandcloses thereby giving access to each of the mixers. The mixing is done simplybymeans of 2 vertical treesonwhich aremountedscrewsofthe sort used on small boats. The [illegible] of distribution shouldbetaken awaybya hand-winch ... at the same timeasthe ... at the opening of the gang-way entry.
