What reading level is Annual Report of the Board of Regents of the Smithsonian Institution 1909 book?
To quickly assess the difficulty of the text, read a short excerpt:
We can not ignore the existence of the facts, and as scien- tific men we can not let them alone, while they insistently rise at every turn in our pathway and demand investigation. True it is that they bring in their train whatever is fundamental in biological inquiry — ^heredity, the direct influence of the environment, and differ- ences in the properties of protoplasm in different plants. It is not customary, however, in laboratories worthy of the name, to shun investigations that approach to ...the deep mysteries of life. There is every reason why students of ecological problems should seek, not shun, this difficult but hopeful line of study. I say hopeful advisedly, for within the past three years there have come under my observation various definite cases of adjustment in plants, some of which have been accurately measured, correlated with external factors, and ex- pressed by curves. Though essentially more difficult, there is no reason, as far as now appears, why the different degrees of adaptation of two species or varieties to a given external factor may not be simi- larly determined and graphically represented, as the expression of a definite difference of physiological activity, as shaped by heredity, iij PLANTS IN ARID REGIONS — SPALDING.
