What reading level is Scientific American Supplement, No. 643, April 28, 1888 book?
To quickly assess the difficulty of the text, read a short excerpt:
Estrade's locomotiveby the learned societies has been the difficulty of supplying boilerpower enough for high speeds contemplated; and he deals atconsiderable length with a large number of English engines of maximumpower, the dimensions and performance of which are too well known toour readers to need reproduction here.
Aware that a prominent weak point in M. Estrade's design is that, nomatter what size we make cylinders and wheels, we have ultimately todepend on the boiler for power, M. Nansou...ty argues that M. Estradehaving provided more surface than is to be found in any other engine, must be successful. But the total heating surface in the engine, whichwe illustrate, is but 1, 400 square feet, while that of the GreatWestern engines, on which he lays such stress, is 2, 300 square feet, and the table which he gives of the heating surface of various Englishengines really means very little. It is quite true that there are noengines working in England with much over 1, 500 square feet ofsurface, except those on the broad gauge, but it does not follow thatbecause they manage to make an average of 53 miles an hour that anaddition of 500 square feet would enable them to run at a speed higherby 20 miles an hour.
