The editors will thankfully receive news items and other matter likely to be of interest to sub¬ 
scribers. Papers will be published, so far as possible, in the order of reception. All extended con¬ 
tributions, at least, should be in the hands of the editor the first of the month preceding publication. 
Contributors are requested to supply electrotypes for the larger illustrations so far as possible. Photo¬ 
engravings may be obtained by authors at cost. The receipt of all papers will be acknowledged.— Eds.

The complexity of nature and the many interrelations existing be¬ 
tween animals and plants and between many representatives of both 
major and minor groups in both kingdoms, renders exhaustive investi¬ 
gation and the reaching of well defined conclusions a matter of great 
difficulty. There has never been more need of solving scientific ques¬ 
tions than at the present because of the more or less direct bearing they 
have upon increased production and the national welfare. The problem 
of the permanent pasture recently discussed by Professor Herbert 
Osborn before the Society for the Promotion of Agricultural Science, is 
only one of many demanding expert knowledge in widely varied lines 
before it can be answered in a satisfactory manner. Entomology is one 
of the special sciences and insects frequently play a most important 
part in inhibiting, sometimes in promoting, greater production, and 
here and there insects react upon other groups and are in turn reacted 
upon. The solution of a general problem such as that mentioned 
above is proportional to our knowledge of the least understood group 
exercising a vital influence upon the environment. There is need, as 
pointed out by Professor Osborn, for a more comprehensive, better 
coordinated study in the case of general problems. Such work may be 
conducted under the direction of a well recognized authority along 
general lines, capable of bringing to his aid such expert assistance as 
may be necessary or the same end may be attained by the specialist 
seeking the cooperation of others and arranging for a harmonious 
prosecution of all necessary special studies in relation to the general 
problem. There are a limited number of the former group at liberty to 
undertake the supervision of new lines of study and comparatively few 
individuals in this class are in a position to appreciate the significance
