The chart is 147 feet long, 54 inches wide, exclusive of the 
important data condensed on a separate 8-foot sheet. This is only 
a preliminary chart, as may be seen from the condensed data attached, 
which shows that of the 822 persons represented on the chart 539 are 
of mature age. The unknown persons represent 303, unknown 
ability; 336, unknown height; 339, unknown weight ; 348, unknown 
health. The family is remarkable for the health of its members, having 
so far only 97 deaths. The oldest child, Generation ll-i, was born in 
1827. There are, of couise, a large number of persons on the chart 
who are rather young. Where a person has more than one ability well 
marked, such as music and literary ability, or music and business 
ability, or constructive and business ability, the chart shows only one 
ability. There are several cases where persons have three well marked 
abilities. In all cases, the following is the rank on the chart :— 
Literary ability is always charted. Following this, music and then 
art, and then constructive. Constructive ability represents those 
persons who have a decided mathematical and mechanical turn of 
mind, who are builders, contractors, carpenters of advanced standing, 
architects and men of these classes. Under “ Various ” abilities are 
classified business, agricultural and domestic abilities. These are not 
marked on the chart. 
It will be noticed under “ Diseases ” that a majority of the 
persons who have died were infants, and even among infants the deaths 
are remarkable for their small number considering the conditions under 
which the people of the third generation of this family had to live. The 
paternal ancestor, Generation I., came to America in 1842, dying 
two years later, and his children came to Utah among the early 
settlers, 1847-52. Many of the third generation were born in this 
State under conditions that are not by any means comparable to those 
existing in communities that have been settled for many years. The
