 MANY MORE SUBSCRIPTIONS NEEDED 



In order to pay the cost of publishing the nine numbers 

 of The Review for 1906 very many more subscriptions at $1 each 

 will be required. The above statement is based on an estimate 

 which does not include the cost of the business management, which 

 has from the beginning been carried by a secretary under the 

 direction and at the expense of the Managing Editor, who has 

 acted as publisher because regular publishing houses wish to charge 

 for office expenses and profits several hundred dollars more than the 

 salary of a secretary. 



It is absolutely necessary that The Review should be made 

 nearly self-supporting this year and completely so next year. Do 

 the numbers already published convince you that there is a need of 

 such a journal^ and will you co-operate by subscribing and by recom- 

 mending it to others? 



VOLUME I TO 1906 SUBSCRIBERS FOR 50 CENTS. 



Many new subscribers have written that they sent orders 

 without knowledge of the offer of Vol. I for 50 cents. We still 

 have a number ot complete sets and the price is 50 cents to those 

 who have already sent $1 for the 1906 volume. Or send $1.50 

 for all issues of 1905 and 1906. Orders must be direct to the 

 publisher. 



VOLUME I, BOUND FOR $1.25, OR $1.90 WITH SUBSCRIPTION 



FOR- 1906 



Orders at these rates must be direct to publisher. 



EXTRA NUMBERS OF VOL. I AT 10 CENTS EACH 



We have on hand after making up complete sets a number 

 of extra copies of most issues of Vol. I, 1905. Many subscribers 

 are completing their sets and several schools have ordered dozens 

 to be used in classes.
