Foreword 



The editor wants yotir help. We are publishing in the advertis- 

 ing pages of this number some very attractive clubbing offers. 

 There is an exceptional offer to new subscribers also. Any new 

 subscriber sending in four new subscriptions may have his sub- 

 scription free for a year. These liberal offers are made because 

 we want new subscribers. The subscription list has increased 

 in the last six months ten per cent: this in spite of vigorous 

 pruning to get out all dead timber. We have never pruned as 

 closely. We have never had so many subscribers. We are 

 getting a good line of advertising: thanks to the vigorous work 

 of the Co:mstock Publishing Co:mpany. All this is duly appre- 

 ciated we know for the office is in receipt of :.niany letters of co:ni- 

 mendation. The Review is a well established organ. But it is 

 right at the point now where its efficiency would be multiplied 

 many times if we could double otu" subscription list. Advertising 

 pays in proportion to the number of readers. The advertising 

 would pay for the expense of publication if we had five thousand 

 subscribers and that is asking little. We could then begin to 

 buy articles that would be even more attractive. We could 

 reduce the price of the Review. The editor can not reach these 

 new subscribers. You can! If each reader will win one new 

 subscriber we can begin to improve rapidly. Will you not do 

 that much for the Nature Study Movement !
