Moshe Feldenkrais was a man of precision. I understand that his biography written by Mark Reese was based on the memories of several people gathered after many years. However I think some of the informations could be more precised. „Kremenets was not on the rail line that stopped in Slavuta, but it was not so far from the Pshater (his grandfather) household (…) Among the jurneys to Slavuta- four hours each way in a horse drawn cart …” The distance from Kremenets to Slavuta is 186 km. It was not possible to make the journey by horse – cart during four hours even during peace.
And those events took place during the time of the I-st World War. The jurney could take even 2-3 days. They had to travel first by train from Kremenets (pol. Krzemieniec) probably to Równe by Kamienica and Zdołbunów and than 4 hours (6-7 hours more probably) by horse-cart from Równe to Slavuta. It is important. The travel for grandfather’s birthday was an event much more important than a family visit in the surroundings of a leaving place. And a journey by train took several hours probably, with changing of trains at least one time, (most probably two Times) plus 6-7 hours of a horse -cart ride. If we read later on that the grand father’s birthday was attended by 103 guests „most of them family members, many of tchem dignitaries” and Moshe remembered sitting on his grand pa laps „sat like a king at the table” and if we take into consideration the fact that his grandpa was an important businessman in Slawuta importing wood from all over Russia and producing high quality char coal for the Polish noble family Sanguszko that owned textile factories this make the real sense and importnace of those facts to the child Feldenkrais was. Here is a map of railway system from 1939. It probably did not change very much from 1915 in the Eastern parts of the Poland territory recuperated in 1918 and lost in 1939.
