It has long been known that Russian cities are not clean. According to the research of Professor Jacob, in Kharkov, in the autumn time, as much dust is deposited from the air during 24 hours as in Paris during the whole year. The uncleanness of our cities depends on poor supervision over the cleaning of sewage from the streets, from poor paving and from insufficient watering them in summer in dry weather. There are a lot of cities in our country that are not paved at all and watering of the streets is not done everywhere. Kazan is one of the largest and best cities in Russia, although it is paved, according to the primitive method, with limestone, but in summer the streets in it are not watered, except for the main one, Voskresenskaya; and the last street is only occasionally and little by little watered.
Давно извѣстно, что русскіе города не отличаются чистотою. По изслѣдованіямъ профессора Якобія въ Харьковѣ, въ осеннее время, осѣдаетъ изъ воздуха въ теченіе 24-хъ часовъ столько пыли, сколько въ Парижѣ осѣдаетъ въ теченіи цѣлаго года. Нечистота нашихъ городовъ зависитъ отъ плохого надзора за уборкою нечистотъ съ улицъ, отъ плохого мощенія и отъ недостаточной поливки ихъ лѣтомъ въ сухое время. Очень много городовъ у насъ совсѣмъ не мощеныхъ и поливка улицъ не вездѣ производится. Казань одинъ изъ самыхъ большихъ и лучшихъ городовъ въ Россіи, хотя и вымощенъ, по первобытному способу, известнякомъ, но лѣтомъ улицы въ немъ не поливаются, кромѣ главной, Воскресенской; да и послѣдняя улица только изрѣдка и по немногу поливается.
