ECONOMIC BNTOMOLOGY:

(Concluded from p. 201.) 
Beucium also has found the need of legislation to compel the 
destruction of insects. Rewards were formerly given, but it has 
been found requisite to resort to compulsion. I have not the 
Belgian code at hand to refer to, but I believe it is left to an 
arrete royale to direct from time to time the measures to be taken. 
In considering the results of experiences of other nations, and 
comparing compulsory action with action for rewards, it will not 
be forgotten that, eleven years ago, the Central Agricultural 
Society of Saxony made efforts to secure united action among 
landowners, and urged the magistrates to assist in getting the 
insects collected. The influence of the society was sufficiently 
great to secure large numbers being destroyed. This, however, 
seems to have been a result to be regarded as an exception rather 
than a rule, and the united action was the more readily obtained 
since the year was an exceptionally bad one as to damage from 
cockchaffers. 
America, foo, has found the need of. legislation in some 
States,* instead of relying on bounties only. There the ravages 
are on so gigantic a scale, and inventions and arrangements for 
destroying locusts are kept so prominently before the public, that 
it might be readily imagined that the need for voluntary united 
* The laws are given in full in the report of the State Entomologist for Missouri, 
1877, and in the report of the United States Entomological Commission. The 
French laws I referred to at greater length because the information is not so 
accessible, as a fire at the office destroyed nearly all the copies of the ‘Journal 
Officiel,’ from which I have quoted.
