147. A Diversion similar to the above is peculiar to the _North of Europe_, practised by the Russians, particularly the Inhabitants of Zarsko Zelo; and accompanied with a Sensation _so delightful_, that they seek it in the _open_ Air, amidst the _utmost Severity_ of the _Frost_. It is a Sort of Boat or _Car_, in which they _glide_, for a considerable Distance, _down_ an _artificial_ Declivity of _waved_ and _polished_ Ice: being drawn up by Servants; they launch precipitately forwards, and _down_ again as before. [Sidenote: Amusements of Gestation in common with the Balloon.] 148. _Sledges_ drawn _swiftly_ over the undulated Surface of a _snowy_ Country, a favourite Diversion in many Parts of Germany, in Lapland, and Siberia: Skaiting on _level_ Ice; the Motion of a Vessel on _smooth_ Water; of a _fleet_ Horse; also of Wheel-Carriages rolling over +even+ Gravel, or a _grassy_ Plain, are each a _Luxury_ of the same Kind; and _grateful_ to the Nerves. [Sidenote: Vertical Flying-Coach.] 149. There is yet another Amusement, which is said to be of _German_ Extraction, still frequent in the North of England, called the _vertical_ +Flying-Coach+.[40] Two Persons are required to turn the Machine (when full): which moves like the four Sails of a Windmill: a Seat being placed at the End of each Sail. 150. The _Pleasure_ communicated to the _Nerves during_ the Descent, is to some Constitutions so _exquisite_, as to be full as much as the human Frame can support: others are affected by it in a _gentler_ Manner. These different Diversions, flowing from the same Principle in common with the Balloon, viz. that of _being carried with a gentle Motion_, are _one or other_ suited to all Ranks and Ages. 151. The Pleasure of the double Slack Ropes, when seated in the Car appended between them, is perhaps in itself _superior_ to that of most others. 152. The _vertical Flying-Coach_[41] compleats the _Circle_, of which the Slack Rope describes but the lower _Half_. [Sidenote: Balloon and Vertical Flying-Coach compared.] 153. The Sensations communicated by the Motion of the Balloon, come nearest those of the vertical flying Coach, tho’ _more_ gentle, and if possible, _more_ pleasing. [Sidenote: No Sickness or Giddiness in the Balloon.] At Sea, the most experienced Mariner is sometimes _sick_ or _giddy_. 154. Nothing of the Kind happens in the Balloon: where an infinite Variety charms the Imagination. [Sidenote: The Spirits raised.] 155. The Spirits are raised by the _Purity_ of the Air[43], and _rest_ in a _chearful_ Composure. [Sidenote: The Greatest Height conveys no Fear of falling.] 156. Even when _stationary_ above the Clouds, the _Height_ conveys with it no _Danger_ of _falling_: any more than _when_ in a Vessel at Sea, (as off the West-India Islands, for Example) the _Fish_ are seen gliding over the clear _white rocky_ Bottom, at the Depth of twenty Fathom: as the Aironaut seems perfectly unconnected with the Earth, and unconcerned about it.
