a judicious arrangement of our ftudies, and 
difpofition of our time. In the arrangement 
of our fludies we fhould imitate the Ikilful 
agriculturift, whofe fucce.Tive crops fo re- 
lieve each other, as to preclude the neceflity 
of fallowing^ and, as to the difpofition of 
our time, let us take Botany for an exam- 
ple. A man who ftudies all day and every 
day, will, in a few years, become unhealthy 
and ftupid : therefore, part of every Undent's 
time muft be loft in exercife. Loft did I fay ? 
No : it is not loft to a Eotanift. He fludies 
where other men, for want of books, muft 
lounge. To him the book of Nature lies 
conftantly open. He reads as he walks 
along: every field is a new chapter; every 
leaf is an 'object of attention, and every 
flower a prize. A general knowledge of 
Botany therefore may be learnt at times 
when other ftudies are necefTarily fufpend- 
edj confequently it interferes with no other 
fcience. I fay a general knowledge^ which is 
enough for a gentleman who ftudies Botany 
as an amufement: an univerfal and minute 
botanift muft unavoidably neglect things of 
more importance. In my next letter I fhall 
lead you into the fields. Remember to 
p 4 take.
