THIS IS WHAT HAPPENED 



The day after we advertised that last set of Fern Bulletin beginning 

 with volume VI. it was sold, of course. Don't ask us for VoL VI now— 

 it is too late. But we have several sets of this volume which lack only 

 the January number. These are for sale at $1.00 a volume or we will give 

 one absolutely free with an order for volumes 7 to 17 (11 vols.) at $7.00. 

 With this we also include the ten-year index. This is a reduction of $2.25, 

 and you had better hurry at that. If you have some of the later volumes 

 deduct 60 cents for each volume you have and we will send what you lack 

 for the remainder. Get a full set now. There will never be another pub- 

 lication like it I
