The great productive apparatus of the first ones, perfectly organized on the 
practical plane, but less able to catch the critical side of the followed proceedings, 
has to keep pace with the imperfect practical organization of a University institute, 
that, on the other hand, is always attentive in the critical inquiry of its own work. 
These differences evidently reflect in the results, and also in the development of the 
work: the first ones are more constant and methodical, the second ones more disorderly 
and inconstant, but more interested, for interior organization necessities, in having 
their own results soon made known. 
For these and other more contingent reasons, it is necessary that the Presidency 
of the Group should be a patient referee to coordinate, to encourage and to contain 
the work of the centres within the forecasted limits. 
This is not an easy task, even if not scientifically qualified. The risk of being 
pedant or negligent is always present.

2 - ORGANIZATION OF THE EXPERIMENTAL RESEARCHES ON THE PROBLEM OF STRIPS 
BLOCKS FOR SMALL SCALE CARTOGRAPHY 
Commission III Presidency was aware of the responsibility and the risks taken 
when, in keeping faith to the resolutions voted at the Stockholm Congress, had the 
first contacts with different national organizations, to start and organize a second 
cycle of experimental researches, according with the points of view enunciated in the 
preceding paragraph. 
Of these contacts started in the years 1957-58 we gave a synthetical view in the 
report of Commission III “Aerial Triangulation”, presented at the London Congress 
in 1960. In order to complete the historical description of the events that led to start 
the work, we report here wholly that relation: 
“Resolution n° 3 carried by the Commission at the end of the Stockholm Congress, 
recommended to continue the ‘Essais Contrôlés’ also in the period 1956-60 and asked 
the President to fix the new rules, helped by the experience already acquired and by 
consulting the Commission Experts in advance. 
“Moreover, still within the then adopted resolutions, were contained some fun 
damental principles intended to form the track to be followed in the creation of the 
new ‘Essais’. 
“Four out of the five suggestions have been fully respected about the rules pu 
blished in the Summer of 1958, namely: the ‘Essais’ practical character, the candidates’ 
freedom to choose preferred methods, abolition of the obligation to work on a foreign 
polygon, and the candidate’s obligation to supply a detailed report of their work done. 
“The fifth suggestion concerning the increase of discipline and controls during 
works instead was not added as part of the new rules. 
“Many are the reasons for doing this. Above all, both through personal contacts 
and by what has appeared from the Brussels discussion on the rules prepared at first 
by Commission Ill’s Presidency, the desire was clearly expressed of diminishing 
more and more the competition character of the ‘Essais’ giving them instead an expe 
rimental scientific research appearance, inspired by mutual trust and in a spirit of 
full collaboration. 
“It is evident therefore, that severe control measures could never have agreed 
with such spirit-attitude. 
“To increase a proper control, would, on the other hand, have meant a considerable
