GLADSTONE writes : My interest in the work 

 is not onJy lively hut profound. . . . The exhi- 

 bition of one of the very noblest of human char- 

 acters. — Hawarden Castle, Oct. 12, 1869. 



" The loriter leads us into a new field— the daily 

 life and experiences of a Southern gentleman liv- 

 ing with his large family of sons and daughters in 

 the midst of his slaves. It furnishes a picture of 

 the life of a Southern country gentleman of from 

 30 to 40 years of age complete and accurate in 

 detail. It is the life of a proud, guileless, and 

 honorable gentleman— saich a character as Thack- 

 eray loved.^^— St Louis Republican. 



and its First Cause According to Modern 

 Science. From the French. 12mo, cloth, 

 $1.00. 



"Alas, how often is the reader surprised and be- 

 trayed by the catching title page ^Modern Science,^ 

 pasted on books poor in science and literature^ 

 and but too frequently destined to divulgate the 

 unsound and unwholesome doctrines of positiv- 

 ism or materialism. Here, at least, the case is 

 otherwise; for the work of which we speak offers us 

 science of a true and healthy tone in service of 

 the good cause.^^ — From Introduction.

 feeble and the powerful, the great and the insig- 

 nificant is energy — invincible determ^ination — a

7% IMPROVEMENT BONDS. 



Secured by Real Estate worth Four Times the Amount of the Mortgage. 



The attention of investors having money to invest and wishing a little higher rate of interest than is usually realized from Eastern 

 securities, is invited to some bonds that bear 7 per cent, annual interest, and are so amply secured by real estate as to commend them to 

 the most careful and conservative investor. 



These are Improvement Bonds of the Fort Worth and Arlington Heights Land and Invest= 

 ment Co. which owns the beautiful suburban addition to Fort Worth, Texas, known as Arling= 

 ton Heights. They are issued to the amount of $100,000.09, and are for the purpose of erecting 

 a large and commodious Hotel at the Heights. 



The site selected for the building is on very high ground ; it is the most desirable tract in the addition, and includes a full block. Tha 

 hotel and site are mortgaged to secure the bonds, and 100 blocks, of forty lots eacll, are also included in the mortgage. Valuing 

 the blocks at $3,000 each, a security is given of about four dollars' worth of real estate to one dollar's worth of bonds. Surrounding 

 blocks of the same class have been sold for more than $3,000 per block, and the property is constantly increasing in value. 



With its improved and unimproved land. Electric Street Railway, Electric Light Plant, complete Water System, Mortgage Notes, 

 etc., the company possesses assets over liabilities of more than one million of dollars. 



The bonds mature at the rate of $10,000 per year, beginning with January 1st, 1897. The Company has the privilege of calling them 

 all in on and after January 1, 1903. They are issued in denominations of $350 and $500, with the interest payable July 1 and January 1, 

 in coupon form. 



Each $1,000 worth of the bonds is secured by a specified block, which is released as the bond is retired; as the hotel and site remains 

 a mortgage for all of the bonds, the security becomes even stronger as the bonds are paid off. 



The entire mortgaged property is held in trust for the bondholders, by the Franklin Trust Co., of Brooklyn, through whom the interest 

 and principal will be paid. The Trust Company can foreclose in the event of default of interest or principal. 



The bonds bear interest from January 1, 1893. They are sold at par with accrued interest; a large proportion of them have already 

 been sold; the hotel is already in course of construction. 



A few lots can be purchased in this addition which promise large returns after a few years' holding. 



Further information given by letter or private interview.
