TO THOSE WHO HAVE REMITTED FOR 1894. 



W^e feel especially and unusually thankful to those who 

 have sent in their checks during the past five weeks. 



Like others, we are struggling with the "hard times" 

 and your promptness helps materially. We cannot write 

 personally to thank each one, but we take this means of 

 telling you how sincerely we appreciate your thought- 

 fulness. In spite of the times, which we believe will 

 change before mid-summer, we shall be able to increase 

 the number of our illustrations during the year.
