being the simplest, and obviously much the cheapest, appears to me to be preferable 
to the former ; particularly as the architectural effect of any building depends 
more upon the general proportions of the various parts, whether plain or ornamen- 
tal, than on such minutiae as the tints or veins of particular stones. 
54. The wash used for the colouring of cement stucco requires to be renewed after 
a certain period. It may be considered very good, if it can last for two or three 
years. 
55. We are now trying various combinations of all the ingredients known to be 
used by plasterers, in order to endeavour to discover, which are the most useful, 
and which may be rejected as superfluous ; but it will, of course, require some 
months to elapse, before any definitive conclusion can be drawn from these expe- 
riments. We have, however, already satisfied ourselves, that beer grounds and 
cement powder are useless, or rather prejudicial. 
56. The artificial cement made of chalk and blue clay is of an extremely light 
buff coloui, which has a handsome appearance in itself, and requires no colouring. 
§ 8 . — Of Cement Grouting. 
57. Cement may be used as grout for the walls of buildings, by mixing it with 
no more water than will just enable it to run into every crevice. In this state it 
sets very slowly, and rather like a mortar than a cement, but eventually it becomes 
hard and sound. A much greater excess of water will ruin cement altogether, as 
we proved, by putting cement grout into a basin, with about an inch of clear water 
over it. This effect, however, can scarcely take place in grouting a wall of common 
brick work, because the excess of water has an opportunity of running off, or of 
being absorbed by the bricks. 
58. Cement grouting should never he used with gravel to form a concretion for 
the foundations of buildings, it being peculiarly liable to fail in that situation. 
For this important purpose, none but the water limes are applicable, which must 
be pulverized in the state of quick lime, immediately before they are used. One 
measure of such lime to six or seven measures of gravel, are the most common 
proportions. 
II* Of the Original Source of Wealth, and Periodical Increase . 
In answer to the question, what is the original source of wealth and revenue ? I 
find the following passages in the book of Genesis. 
Chapter 1st, 20th verse. “ And God said, Let the waters bring forth abundantly, 
the moving creature that hath life ; and fowl that may fly above the earth, in the 
open firmanent of heaven.” 
22d. “ And God blessed them, saying, Be fruitful and multiply, and fill the waters 
in the seas ; and let fowl multiply in the earth.” 
24th. And God said ; Let the earth bring forth the living creatures after his 
kind, cattle and creeping thing, and beast of the earth, after his kind; and it was 
so.” 
27th. So God created man in his own image, in the image of God created he 
him ; male and female created he them.” 
28th. And God blessed them; and God said unto them, Be fruitful and multiply, 
and replenish the earth, and subdue it.” 
29th. And God said, Behold, I have given you every herb bearing seed, which 
is upon the face of all the earth ; and every tree, in which is the fruit of a tree 
yielding seed; to you it shall be for meat.”
